I'm your navigator, Aoi Shirasagi.鋼橋檢驗報告寫著：Fe 的原子量 = 55.85。如果原子核只由「整數個」質子與中子組成，這個 .85 是從哪裡來的？The steel-bridge report says Fe's atomic weight is 55.85. If a nucleus is made of a whole number of protons and neutrons, where does the .85 come from?縮小裝置啟動！真相，就藏在原子裡。Shrink device on! The truth is hiding inside the atom.Case 1：失衡的同位素反應爐。收集 6 顆質子（Z = 6），重建碳原子核！Case 1: the unbalanced isotope reactor. Collect 6 protons (Z = 6) to rebuild a carbon nucleus!Z 決定元素身分——Z 一變，元素就換人。中子數 N 可以改變，形成同位素；質量數 A ≈ Z + N。Z decides the element — change Z and it's a different element. The neutron number N can vary, giving isotopes; mass number A ≈ Z + N.注意：每收集一顆中子，你的質量變大，重力也跟著變大！Careful: every neutron you collect adds mass — and your gravity grows with it!碳原子核重建完成！你組出的是 C-{A}（Z = 6、N = {N}）。Carbon nucleus rebuilt! You formed C-{A} (Z = 6, N = {N}).天然碳是 C-12 與 C-13 的固定比例混合。週期表上的原子量是各同位素的「加權平均」，所以帶小數點——.85 的真兇，就是同位素！Natural carbon is a fixed mix of C-12 and C-13. The atomic weight on the periodic table is a weighted average of the isotopes — so it has decimals. The culprit behind .85 is the isotope!Case 2：電子的不在場證明。Bohr 說電子沿固定圓形軌道運行——但那是被推翻的證詞。Case 2: The Electron's Alibi. Bohr said electrons ride fixed circular orbits — testimony that has been overturned.發光的圓形「軌道」一踩就碎！請站在藍色電子雲上——那是 Ψ² 機率最高的區域。The glowing circular "orbits" shatter underfoot! Stand on the blue clouds — where Ψ² is highest.軌域電梯：一個軌域最多兩顆電子，而且自旋必須相反。按「切換」改變你的自旋 ↑／↓！Orbital elevators: one orbital holds at most two electrons, with opposite spins. Press Switch to flip your spin ↑/↓!沿路收集副殼層證物（1s²、2s²……），結案時要用來建立鈣的檔案。小心假證物！Collect subshell evidence (1s², 2s², …) — you'll need it to profile calcium at the end. Beware of fakes!不在場證明成立——電子從來就不在任何一個「點」上，只有 (n, ℓ, mℓ, ms) 四個身分編號。The alibi holds — the electron was never at a single point. All it has is its ID: (n, ℓ, mℓ, ms).Case 3：週期表上的側寫。離子風暴中的元素妖會掠奪你的價電子！Case 3: Profiling on the Periodic Table. Element spirits in the ion storm will steal your valence electrons!你的裝甲核心是鈉 Na（χ = 0.9）。看敵人身上的 χ，算出電負度差 Δχ。Your armor core is sodium Na (χ = 0.9). Read each enemy's χ and compute Δχ.Δχ ≥ 1.7 → 切換為「離子鍵護盾」（電子轉移）；Δχ < 1.7 → 切換為「共價鍵鎖定」（共用電子）。按「切換」換模式，按 Space 發射符咒！Δχ ≥ 1.7 → Ionic Shield (electron transfer); Δχ < 1.7 → Covalent Lock (shared electrons). Press Switch to change mode, Space to throw a talisman!核心切換為氯 Cl（χ = 3.0）！同為鹵素的敵人現在和你電負度相近——重新計算 Δχ！Core switched to chlorine Cl (χ = 3.0)! Fellow halogens now have a similar χ to yours — recompute Δχ!動機只有一個：把最外層湊成 8 個電子——不是搶、就是送、不然就共用。Δχ 的大小直接預告鍵結型態。One motive only: complete an outer shell of 8 — take, give, or share. The size of Δχ predicts the bond type.Case 4：引力與斥力的角力。解離巨獸正企圖拉斷鋼骨大樓的晶格鍵結！Case 4: Forces at War. The Entropy Crack is trying to tear apart the steel tower's lattice bonds!看上方儀表：r > r₀ 時淨力為引力——對牠發射「引力符咒」，把鍵長拉回來！Watch the gauge: when r > r₀ the net force is attractive — throw attraction talismans to pull the bond back!r < r₀ 時斥力急遽上升——踩著斥力原子核彈起，從上方反擊牠的頭頂！When r < r₀ repulsion soars — bounce off the repulsion nuclei and strike its head from above!牠疲勞時，站到金色鍵結鎖定栓前，在 r = r₀ 的瞬間按 Space，把鍵結鎖在位能井底 E₀！When it tires, stand at the golden bond-lock bolt and press Space the instant r = r₀ to lock the bond at the bottom of the well, E₀!鍵結鎖定完成！井越深（E₀ 大）→ 熔點越高；井底越陡 → 彈性模數越大；井越不對稱 → 熱膨脹越大。Bond locked! Deeper well (larger E₀) → higher melting point; steeper well bottom → higher elastic modulus; more asymmetric well → larger thermal expansion.哈哈哈！所有的鍵都會被我拉斷——熵永遠是贏家！Ha ha ha! I'll tear every bond apart — entropy always wins!拉不斷？那就把你們全部壓碎！Can't pull you apart? Then I'll crush you together!怎……怎麼可能……力量……竟然平衡了……Im... impossible... the forces... are balanced...最後一步：用你蒐集的副殼層證物，建立鈣 Ca（Z = 20）的完整電子組態——鈣是水泥化學的主角！Final step: use your subshell evidence to build the full electron configuration of calcium Ca (Z = 20) — the star of cement chemistry!完全正確！Ca：1s² 2s² 2p⁶ 3s² 3p⁶ 4s²。價電子 2 個（4s²）——Ca 失去它們成為 Ca²⁺。真相永遠只有一個！Exactly right! Ca: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². Two valence electrons (4s²) — lose them and Ca becomes Ca²⁺. There is only one truth!推理有破綻！提示：沿對角線規則 1s → 2s → 2p → 3s → 3p → 4s 填入，電子總數必須等於 Z = 20；ℓ 只能是 0 ~ n−1。There's a hole in your deduction! Hint: follow the diagonal rule 1s → 2s → 2p → 3s → 3p → 4s; the total must equal Z = 20, and ℓ can only be 0 to n−1.「原來這棟大樓能耐震，全靠平衡距離 r₀ 與位能井 E₀ 的深淺啊！」"So this tower survives earthquakes all thanks to the equilibrium distance r₀ and the depth of the energy well E₀!"發光的原子核會產生強大斥力。貼近時按跳躍，借斥力高高彈起！Glowing nuclei push back hard. Jump right next to one to ride the repulsion skyward!看到金色鍵結點了嗎？按「鉤爪」發射共價鍵鏈盪過去，再按一次放開！See the gold bonding node? Press Grapple to fire a covalent chain and swing — press again to let go!不穩定的軌道一踩就會崩塌，快速通過！Unstable orbits crumble the moment you land — keep moving!鍵結鎖定柱！站在柱前按 Space 開始校準，指針到 r₀（FN = 0）時再按一次！A bond-lock pillar! Stand by it and press Space to start calibrating, then press again when the needle hits r₀ (FN = 0)!量子衝刺：每次離地可衝刺一次，空中也能使用！Quantum Dash: one dash per jump — it works in mid-air!自由電子海：金屬鍵的價電子不屬於任何原子。在這裡可以高速滑行！Electron sea: metallic valence electrons belong to no single atom. Glide through at high speed!離子磁壁：陰陽離子的庫倫引力會吸住你。貼牆時按跳躍可以蹬牆跳！Ionic walls: the Coulomb attraction between ± ions holds you. Jump while clinging to wall-jump!電梯上已有一顆 ↑ 電子。先切換成 ↓ 自旋再進入！This elevator already holds a ↑ electron. Switch to ↓ spin before boarding!包立不相容！兩顆電子不能擁有完全相同的四個量子數——請切換自旋！Pauli exclusion! Two electrons can't share all four quantum numbers — flip your spin!假證物！{X} 不存在：ℓ 只能是 0 ~ n−1。Fake evidence! {X} doesn't exist: ℓ can only be 0 to n−1.取得證物 {X}Evidence found: {X}Z = {Z} → {E}：Z 一變，元素就換人！Z = {Z} → {E}: change Z, change the element!N = {N}：質量數 A = {A}，重力 ×{G}N = {N}: mass number A = {A}, gravity ×{G}鳥居未開啟：需要 Z = 6（目前 Z = {Z}）。The torii is sealed: Z = 6 required (now Z = {Z}).鳥居未開啟：碳的穩定原子核需要 N ≥ 6（目前 N = {N}）。The torii is sealed: a stable carbon nucleus needs N ≥ 6 (now N = {N}).離子鍵！Δχ = {D} → 電子轉移成功Ionic bond!

Collect 6 protons (Z = 6) and at least 6 neutrons (N ≥ 6), then reach the golden torii.• 紅色 ⊕ 是質子，灰色 n 是中子。每撿一顆中子你就變重，重力也變大。
• 貼近發光的原子核按「跳躍」，借斥力高高彈起（斥力反衝）。
• 金色鍵結點按「鉤爪」盪過深淵，盪到最高點再按「跳躍」脫離。
• 鍵結鎖定柱：站在柱前按 Space，指針到 r₀ 時再按一次，就會搭起橋。
• 紅色鳥居要答對推理題才會開啟；石燈籠是檢查點。• Red ⊕ = proton, grey n = neutron. Each neutron makes you heavier — gravity rises.
• Jump right next to a glowing nucleus to ride the repulsion skyward (Repulsive Bounce).
• Grapple gold nodes to swing over pits; jump at the top of the swing to let go.
• Bond-lock pillar: press Space beside it, then again when the needle hits r₀ to build a bridge.
• Red torii open after a deduction quiz; stone lanterns are checkpoints.原子序 Z = 質子數，Z 一變元素就換人。質量數 A ≈ Z + N，中子數不同的同一元素稱為同位素。週期表上的原子量是各同位素的加權平均：Ā = Σ fiAi，所以幾乎不會是整數。Atomic number Z = number of protons; change Z and the element changes. Mass number A ≈ Z + N; same element, different N = isotopes. The atomic weight on the periodic table is a weighted average Ā = Σ fiAi, so it is almost never a whole number.證明電子的「不在場證明」：電子沒有固定軌道，只有機率分布與四個量子數 (n, ℓ, mℓ, ms)。沿路收集正確的副殼層證物，抵達終點。Prove the electron's alibi: it has no fixed orbit — only a probability cloud and four quantum numbers (n, ℓ, mℓ, ms). Collect the genuine subshell evidence and reach the exit.• 發光的橘色 Bohr 圓軌道一踩就碎，要快速通過；藍色電子雲（Ψ² max）才站得穩。
• 軌域電梯上已有一顆電子：先按「切換」把自旋改成相反方向，才能搭乘。
• 小心假證物：2d²、1p⁶、3f² 不存在（ℓ 只能是 0 ~ n−1），撿到會扣血。
• 藍色鬼火會瞬移，用符咒（Space）擊退。• Glowing orange Bohr orbits crumble — cross quickly; blue Ψ² clouds are safe.
• Orbital elevators already hold one electron: press Switch to flip your spin before boarding.
• Beware fake evidence: 2d², 1p⁶, 3f² can't exist (ℓ = 0 to n−1) and will hurt you.
• Blue wisps teleport — hit them with talismans (Space).Bohr 模型的「能階量子化」是對的，被推翻的是「確定軌道」；波動力學以機率分布描述電子。ℓ = 0 ~ n−1；mℓ = −ℓ ~ +ℓ（1、3、5、7 個軌域）；ms = ±½。包立不相容原理：一個軌域最多 2 個自旋相反的電子 → 第 n 殼層最多 2n² 個電子。Bohr was right that energy is quantized but wrong about fixed orbits; wave mechanics uses probability. ℓ = 0 to n−1; mℓ = −ℓ to +ℓ (1, 3, 5, 7 orbitals); ms = ±½. Pauli exclusion: at most 2 opposite-spin electrons per orbital → 2n² per shell.擊退掠奪價電子的元素妖。依電負度差 Δχ 選擇正確的鍵結模式，通過離子風暴走廊抵達終點。Defeat the element spirits stealing your valence electrons. Pick the right bond mode from the electronegativity difference Δχ and reach the exit.• Δχ = |敵人的 χ − 你的核心 χ|，敵人頭上會顯示。
• Δχ ≥ 1.7 → 切換成「離子鍵護盾」；Δχ < 1.7 → 切換成「共價鍵鎖定」。按「切換」換模式，按 Space 發射符咒。
• 模式正確時，敵人的掠奪光束也會被擋下。
• 中途核心會從 Na（χ = 0.9）換成 Cl（χ = 3.0），記得重算 Δχ！
• ± 離子磁壁可以吸附，貼牆時按跳躍可蹬牆往上爬；藍色電子海可以高速滑行。• Δχ = |enemy χ − your core χ|, shown above each enemy.
• Δχ ≥ 1.7 → Ionic Shield; Δχ < 1.7 → Covalent Lock. Press Switch to change, Space to throw.
• The right mode also blocks the enemy's draining beam.
• Midway your core changes from Na (χ = 0.9) to Cl (χ = 3.0) — recompute Δχ!
• Cling to ± ionic walls and jump to wall-climb; glide fast through the blue electron sea.價電子決定鍵結：所有鍵結的動機都是湊滿最外層（八隅體）。電負度 χ 越往週期表右上越大（F 最大）。Δχ 大 → 電子轉移 → 離子鍵（非方向性、硬脆）；Δχ 小 → 電子共享 → 共價鍵（具方向性）。%離子性 = {1 − exp[−(Δχ)²/4]} × 100%。Valence electrons drive bonding — every atom wants a full outer shell (octet). χ grows toward the upper right (F is highest). Large Δχ → transfer → ionic (non-directional, hard, brittle); small Δχ → sharing → covalent (directional). %IC = {1 − exp[−(Δχ)²/4]} × 100%.阻止解離巨獸拉斷鋼骨晶格：把兩原子的間距 r 拉回平衡距離 r₀，並在 FN = 0 的瞬間完成 3 次「鍵結鎖定」。Stop the Entropy Crack from tearing the steel lattice: bring the spacing r back to r₀ and land 3 bond locks at the instant FN = 0.① 拉伸階段（r > r₀）：站在地上面向巨獸，連按 Space 發射引力符咒，把 r 壓回 1.00。
② 壓縮階段（r < r₀）：地上出現兩顆斥力原子核。貼近按跳躍彈起，落在巨獸頭上踩牠，r 就會回升；小心地面衝擊波。
③ 巨獸疲勞：跑到中間的金色鎖定栓前按 Space，等指針到 r₀ 再按一次。
④ 重複 3 次即可擊倒巨獸。① Tension (r > r₀): stand facing the beast and spam Space to throw attraction talismans until r returns to 1.00.
② Compression (r < r₀): two repulsion nuclei appear. Jump beside one to launch, land on the beast's head to push r back up; dodge the shock waves.
③ Exhausted: go to the golden bolt in the middle, press Space, then again when the needle hits r₀.
④ Repeat 3 times to win.FN = FA + FR；r₀ 處淨力為零，且位能 EN 最低（= E₀，鍵結能）。F = dE/dr。井越深 → 熔點越高；井底越陡 → 彈性模數越大；井越不對稱 → 熱膨脹係數越大。FN = FA + FR; at r₀ the net force is zero and EN is minimum (= E₀, the bonding energy). F = dE/dr. Deeper well → higher melting point; steeper well → higher elastic modulus; more asymmetric well → larger thermal expansion.目前 Z = {Z}/6、N = {N}/6。{M}Now Z = {Z}/6, N = {N}/6. {M}繼續往右收集質子與中子吧！Keep heading right and collect protons and neutrons!數量足夠了，衝向終點的金色鳥居！That's enough — run to the golden torii!你目前的自旋是 {S}，已收集 {E} 件證物。遇到電梯時，請切換成與電梯上那顆電子相反的自旋。Your spin is {S}; evidence collected: {E}. At an elevator, switch to the opposite spin of the electron already there.核心：{C}（χ = {X}），模式：{M}。先看敵人的 Δχ，再決定要不要切換模式。Core: {C} (χ = {X}), mode: {M}. Check each enemy's Δχ before choosing your mode.【拉伸階段】r = {R} r₀ > r₀，淨力為引力 → 面向巨獸連按 Space 發射引力符咒！（已鎖定 {L}/3）[Tension] r = {R} r₀ > r₀ — net force is attractive → face the beast and spam Space!

• 小心假證物：2d²、1p⁶、3f² 不存在（ℓ 只能是 0 ~ n−1），撿到會扣血。
• 藍色鬼火會瞬移，用符咒（Space）擊退。• Glowing orange Bohr orbits crumble — cross quickly; blue Ψ² clouds are safe.
• Orbital elevators already hold one electron: press Switch to flip your spin before boarding.
• Beware fake evidence: 2d², 1p⁶, 3f² can't exist (ℓ = 0 to n−1) and will hurt you.
• Blue wisps teleport — hit them with talismans (Space).Bohr 模型的「能階量子化」是對的，被推翻的是「確定軌道」；波動力學以機率分布描述電子。ℓ = 0 ~ n−1；mℓ = −ℓ ~ +ℓ（1、3、5、7 個軌域）；ms = ±½。包立不相容原理：一個軌域最多 2 個自旋相反的電子 → 第 n 殼層最多 2n² 個電子。Bohr was right that energy is quantized but wrong about fixed orbits; wave mechanics uses probability. ℓ = 0 to n−1; mℓ = −ℓ to +ℓ (1, 3, 5, 7 orbitals); ms = ±½. Pauli exclusion: at most 2 opposite-spin electrons per orbital → 2n² per shell.擊退掠奪價電子的元素妖。依電負度差 Δχ 選擇正確的鍵結模式，通過離子風暴走廊抵達終點。Defeat the element spirits stealing your valence electrons. Pick the right bond mode from the electronegativity difference Δχ and reach the exit.• Δχ = |敵人的 χ − 你的核心 χ|，敵人頭上會顯示。
• Δχ ≥ 1.7 → 切換成「離子鍵護盾」；Δχ < 1.7 → 切換成「共價鍵鎖定」。按「切換」換模式，按 Space 發射符咒。
• 模式正確時，敵人的掠奪光束也會被擋下。
• 中途核心會從 Na（χ = 0.9）換成 Cl（χ = 3.0），記得重算 Δχ！
• ± 離子磁壁可以吸附，貼牆時按跳躍可蹬牆往上爬；藍色電子海可以高速滑行。• Δχ = |enemy χ − your core χ|, shown above each enemy.
• Δχ ≥ 1.7 → Ionic Shield; Δχ < 1.7 → Covalent Lock. Press Switch to change, Space to throw.
• The right mode also blocks the enemy's draining beam.
• Midway your core changes from Na (χ = 0.9) to Cl (χ = 3.0) — recompute Δχ!
• Cling to ± ionic walls and jump to wall-climb; glide fast through the blue electron sea.價電子決定鍵結：所有鍵結的動機都是湊滿最外層（八隅體）。電負度 χ 越往週期表右上越大（F 最大）。Δχ 大 → 電子轉移 → 離子鍵（非方向性、硬脆）；Δχ 小 → 電子共享 → 共價鍵（具方向性）。%離子性 = {1 − exp[−(Δχ)²/4]} × 100%。Valence electrons drive bonding — every atom wants a full outer shell (octet). χ grows toward the upper right (F is highest). Large Δχ → transfer → ionic (non-directional, hard, brittle); small Δχ → sharing → covalent (directional). %IC = {1 − exp[−(Δχ)²/4]} × 100%.阻止解離巨獸拉斷鋼骨晶格：把兩原子的間距 r 拉回平衡距離 r₀，並在 FN = 0 的瞬間完成 3 次「鍵結鎖定」。Stop the Entropy Crack from tearing the steel lattice: bring the spacing r back to r₀ and land 3 bond locks at the instant FN = 0.① 拉伸階段（r > r₀）：站在地上面向巨獸，連按 Space 發射引力符咒，把 r 壓回 1.00。
② 壓縮階段（r < r₀）：地上出現兩顆斥力原子核。貼近按跳躍彈起，落在巨獸頭上踩牠，r 就會回升；小心地面衝擊波。
③ 巨獸疲勞：跑到中間的金色鎖定栓前按 Space，等指針到 r₀ 再按一次。
④ 重複 3 次即可擊倒巨獸。① Tension (r > r₀): stand facing the beast and spam Space to throw attraction talismans until r returns to 1.00.
② Compression (r < r₀): two repulsion nuclei appear. Jump beside one to launch, land on the beast's head to push r back up; dodge the shock waves.
③ Exhausted: go to the golden bolt in the middle, press Space, then again when the needle hits r₀.
④ Repeat 3 times to win.FN = FA + FR；r₀ 處淨力為零，且位能 EN 最低（= E₀，鍵結能）。F = dE/dr。井越深 → 熔點越高；井底越陡 → 彈性模數越大；井越不對稱 → 熱膨脹係數越大。FN = FA + FR; at r₀ the net force is zero and EN is minimum (= E₀, the bonding energy). F = dE/dr. Deeper well → higher melting point; steeper well → higher elastic modulus; more asymmetric well → larger thermal expansion.目前 Z = {Z}/6、N = {N}/6。{M}Now Z = {Z}/6, N = {N}/6. {M}繼續往右收集質子與中子吧！Keep heading right and collect protons and neutrons!數量足夠了，衝向終點的金色鳥居！That's enough — run to the golden torii!你目前的自旋是 {S}，已收集 {E} 件證物。遇到電梯時，請切換成與電梯上那顆電子相反的自旋。Your spin is {S}; evidence collected: {E}. At an elevator, switch to the opposite spin of the electron already there.核心：{C}（χ = {X}），模式：{M}。先看敵人的 Δχ，再決定要不要切換模式。Core: {C} (χ = {X}), mode: {M}.

氯有兩種同位素：³⁵Cl（34.969 amu，75.77%）與 ³⁷Cl（36.966 amu，24.23%）。Cl 的平均原子量約為？Chlorine has two isotopes: ³⁵Cl (34.969 amu, 75.77%) and ³⁷Cl (36.966 amu, 24.23%). Its average atomic weight is about?35.00 amu35.00 amu35.45 amu35.45 amu35.97 amu35.97 amu36.00 amu36.00 amuĀ = Σ fiAi = 0.7577(34.969) + 0.2423(36.966) = 35.45 amu。原子量是加權平均，不是簡單平均。Ā = Σ fiAi = 0.7577(34.969) + 0.2423(36.966) = 35.45 amu — a weighted, not simple, average.
為什麼週期表上 Fe 的原子量是 55.85，而不是整數？Why is iron's atomic weight 55.85 instead of a whole number?實驗室秤量誤差造成Laboratory weighing error電子的質量加上去造成The electrons' mass adds the decimals量到的是各同位素依存在比例的加權平均It is a weighted average over the naturally occurring isotopes中子會隨時間衰變Neutrons decay over time我們量到的從來不是「一顆」原子，而是一整群不同同位素的混合，原子量 Ā = Σ fiAi。We never weigh "one" atom — we weigh a mixture of isotopes, so Ā = Σ fiAi.
鈰 Ce 的同位素：¹⁴⁰Ce 佔 88.45%、¹⁴²Ce 佔 11.11%，其餘極少。不用計算機，Ce 的原子量最接近？Cerium: ¹⁴⁰Ce is 88.45% and ¹⁴²Ce is 11.11%, the rest tiny. Without a calculator, Ce's atomic weight is closest to?137.9137.9139.0139.0140.1140.1141.9141.9答案一定緊貼比例最大的 ¹⁴⁰Ce（139.905），再被 ¹⁴²Ce 往上拉一點 → 約 140.12 amu。It must hug the dominant ¹⁴⁰Ce (139.905), pulled up slightly by ¹⁴²Ce → about 140.12 amu.
下列哪一組量子數 (n, ℓ, mℓ, ms) 不可能存在？Which set of quantum numbers (n, ℓ, mℓ, ms) is impossible?(2, 1, 0, +½)(2, 1, 0, +½)(3, 2, −1, +½)(3, 2, −1, +½)(2, 2, 1, −½)(2, 2, 1, −½)(1, 0, 0, −½)(1, 0, 0, −½)ℓ 只能是 0 ~ n−1。n = 2 時 ℓ 最大為 1，所以 ℓ = 2（2d）不存在。ℓ ranges from 0 to n−1. For n = 2, ℓ ≤ 1, so ℓ = 2 (a "2d") cannot exist.
(3, 2, −1, +½) 描述的電子位於哪一個副殼層？The electron (3, 2, −1, +½) is in which subshell?3s3s3p3p3d3d4d4dn = 3 → 第 3 殼層（M）；ℓ = 2 → d。mℓ = −1 是 5 個 d 軌域之一，ms = +½ 為自旋向上。n = 3 → shell M; ℓ = 2 → d. mℓ = −1 is one of five d orbitals; ms = +½ is spin-up.
第 n = 3 殼層最多可以容納幾個電子？How many electrons can the n = 3 shell hold at most?8899181832322n² = 2 × 3² = 18：3s (2) + 3p (6) + 3d (10) = 18。根源是包立不相容原理：每個軌域最多 2 個自旋相反的電子。2n² = 2 × 3² = 18: 3s (2) + 3p (6) + 3d (10). The root cause is Pauli exclusion: two opposite-spin electrons per orbital.
MgO：χMg = 1.2、χO = 3.5。依 %離子性 = {1 − exp[−(Δχ)²/4]} × 100%，約為？MgO: χMg = 1.2, χO = 3.5. Using %IC = {1 − exp[−(Δχ)²/4]} × 100%, the ionic character is about?12%12%51%51%73%73%95%95%Δχ = 2.3；(2.3)²/4 = 1.32；exp(−1.32) = 0.267 → (1 − 0.267) × 100% ≈ 73%。Δχ = 2.3; (2.3)²/4 = 1.32; exp(−1.32) = 0.267 → (1 − 0.267) × 100% ≈ 73%.
Na（…3s¹）與 Cl（…3s² 3p⁵）相遇時，最可能發生什麼事？When Na (…3s¹) meets Cl (…3s² 3p⁵), what most likely happens?兩者各拿出一個電子共用，形成共價鍵Each shares one electron — a covalent bondNa 把 3s 電子交給 Cl，形成 Na⁺ 與 Cl⁻ 的離子鍵Na gives its 3s electron to Cl, forming an ionic bond between Na⁺ and Cl⁻Cl 把電子交給 NaCl gives an electron to Na形成電子海的金屬鍵They form a metallic electron seaΔχ = 3.0 − 0.9 = 2.1（離子性約 67%）。Na 送出 1 個、Cl 收下 1 個，雙方都達到惰性氣體組態。Δχ = 3.0 − 0.9 = 2.1 (~67% ionic). Na gives one, Cl takes one — both reach a noble-gas configuration.
為什麼混凝土、陶瓷等離子性材料又硬又脆？Why are ionic materials such as ceramics and concrete hard but brittle?因為含有很多自由電子They contain many free electrons因為鍵結具有方向性且很弱Their bonds are directional and weak原子面滑移後同性離子相鄰，庫倫斥力使晶體直接斷裂After slip, like-charged ions become neighbours and Coulomb repulsion splits the crystal因為密度太低Their density is too low離子晶體只要滑移半個晶格，原本相鄰的異性離子就變成同性相鄰——滑移 = 斷裂，所以幾乎沒有塑性變形。這正是混凝土需要鋼筋的原因。Slip by half a lattice spacing puts like charges side by side — slip means fracture, so there's almost no plastic deformation. That's why concrete needs rebar.
兩原子位於平衡間距 r₀ 時，下列何者正確？At the equilibrium spacing r₀, which statement is correct?FA 與 FR 都等於零FA and FR are both zeroFN = FA + FR = 0，且位能 EN 最低（= E₀）FN = FA + FR = 0 and the energy EN is minimum (= E₀)位能 EN = 0The energy EN = 0斥力 FR 達到最大Repulsion FR is at its maximumF = dE/dr：淨力為零之處正是 E–r 曲線的最低點。FA 與 FR 並不為零，而是大小相等、方向相反。F = dE/dr: zero net force is exactly the minimum of the E–r curve. FA and FR are not zero — they are equal and opposite.
鍵結能 E₀ 越大（位能井越深）的材料，通常會怎樣？A material with a larger bonding energy E₀ (deeper well) usually has…?熔點越低a lower melting point熔點越高a higher melting point熱膨脹係數越大a larger thermal expansion coefficient彈性模數越小a smaller elastic modulus井越深，要把原子搖散所需的熱能越多 → 熔點 Tm 越高。The deeper the well, the more thermal energy is needed to shake atoms apart → higher Tm.
鑽石（強共價鍵）與鉛（弱金屬鍵）相比，下列何者正確？Comparing diamond (strong covalent) with lead (weak metallic), which is correct?鑽石：井淺而平 → Tm 低、α 大Diamond: shallow, flat well → low Tm, large α鉛：井深而陡 → E 極大Lead: deep, steep well → huge E兩者的 E–r 曲線完全相同Both have identical E–r curves鑽石：井深而陡 → Tm 高、E 極大、α 極小Diamond: deep, steep well → high Tm, huge E, tiny α同一口井解釋三個性質：井深 → 熔點、井底曲率 → 彈性模數、井的不對稱 → 熱膨脹。One well explains three properties: depth → melting point, curvature → elastic modulus, asymmetry → thermal expansion.
