1. Atomic Structure & the Periodic Table | 原子结构与周期表
Start your revision by mastering the fundamentals of the atom. Be able to identify protons, neutrons and electrons, and recall their relative masses (1, 1, 1/1840) and charges (+1, 0, -1). Ensure you can use the atomic number Z and mass number A to calculate the number of neutrons (A – Z) and practise writing nuclide notation such as ²⁷₁₃Al.
从原子的基本构成开始复习。要能辨认质子、中子、电子，记住它们的相对质量 (1, 1, 1/1840) 和电荷 (+1, 0, -1)。要能利用原子序数 Z 和质量数 A 计算中子数 (A – Z)，并练习书写核素符号，如 ²⁷₁₃Al。
ls you the number of outer electrons, and the period number equals the number of occupied shells. For example, oxygen (Z=8) has 2,6 and sits in Group 6, Period 2.
掌握前 20 号元素的电子排布（遵循 2,8,8 原则）。将电子排布与周期表建立联系：族数等于最外层电子数，周期数等于电子层数。例如，氧 (Z=8) 的排布为 2,6，位于第 6 族、第 2 周期。
Observe key patterns in the Periodic Table. Metals are on the left; non‑metals on the right. Reactivity of alkali metals (Group 1) increases down the group, while reactivity of halogens (Group 7) decreases down the group. Be familiar with the properties of Group 1 (soft, low density, vigorous with water), Group 7 (diatomic non‑metals, form salts) and Group 0 (noble gases – unreactive, monatomic).
观察周期表中的关键规律。金属在左侧，非金属在右侧。第 1 族碱金属从上到下反应性增强，第 7 族卤素从上到下反应性减弱。要熟悉第 1 族（质软、密度小、与水剧烈反应）、第 7 族（双原子非金属，能形成盐）和第 0 族（惰性气体——不反应，单原子）的性质。
2. Chemical Bonding: Ionic, Covalent & Metallic | 化学键：离子键、共价键与金属键
Explain ionic bonding as the transfer of electrons between a metal and a non‑metal, forming oppositely charged ions held in a giant ionic lattice. Sodium chloride (Na⁺ and Cl⁻) is the classic example. Remember that ionic compounds have high melting points, conduct electricity when molten or in solution, but are brittle.
解释离子键是金属与非金属之间的电子转移，形成带有相反电荷的离子，这些离子排列在巨型离子晶格中。氯化钠 (Na⁺ 和 Cl⁻) 是经典实例。记住离子化合物具有高熔点，熔融或溶于水时能导电，但质地较脆。
Covalent bonding occurs when non‑metal atoms share electrons to achieve a full outer shell. Distinguish between simple molecular substances (e.g., H₂O, CO₂, CH₄) with low melting points and giant covalent structures (e.g., diamond, SiO₂) that are very hard and have extremely high melting points. Relate properties directly to the type of bonding.
共价键发生在非金属原子之间，它们通过共享电子来达到稳定结构。要区分简单分子物质（如 H₂O、CO₂、CH₄，熔点低）和巨型共价结构（如金刚石、SiO₂，硬度极高，熔点极高）。务必学会将性质与键合类型直接联系起来。
Metallic bonding is described as a lattice of positive metal ions surrounded by a ‘sea’ of delocalised electrons. This explains why metals are malleable (layers can slide) and excellent conductors of electricity and heat.
金属键可描述为正金属离子的晶格沉浸在离域电子的“海洋”中。这解释了为什么金属具有延展性（层与层之间可以滑动）以及优异的导电和导热性。
3. Chemical Formulae & Naming Compounds | 化学式与命名化合物
Writing chemical formulae is an essential skill. Practise the cross‑over method using valency: for magnesium chloride, Mg has a valency of 2 and Cl of 1, so you swap to get MgCl₂. Do the same with group ions: sulfate SO₄²⁻, nitrate NO₃⁻, carbonate CO₃²⁻, hydroxide OH⁻ and ammonium NH₄⁺. For example, calcium nitrate becomes Ca(NO₃)₂.
书写化学式是一项必备技能。反复练习化合价十字交叉法：氯化镁中，Mg 的化合价为 2，Cl 为 1，交叉后得到 MgCl₂。对原子团同样处理：硫酸根 SO₄²⁻、硝酸根 NO₃⁻、碳酸根 CO₃²⁻、氢氧根 OH⁻ 和铵根 NH₄⁺。例如，硝酸钙的化学式为 Ca(NO₃)₂。
Naming compounds follows clear rules. Use prefixes such as mono‑ (omitted for the first element), di‑, tri‑ to name molecular compounds: CO₂ is carbon dioxide, PCl₃ is phosphorus trichloride. When a metal forms more than one ion, use Roman numerals to show the charge: FeCl₂ is iron(II) chloride and FeCl₃ is iron(III) chloride.
化合物的命名有清晰的规则。对于分子化合物使用前缀，如一（第一个元素省略）、二、三：CO₂ 是二氧化碳，PCl₃ 是三氯化磷。当金属可形成多种离子时，用罗马数字表示电荷：FeCl₂ 是氯化铁(II)，FeCl₃ 是氯化铁(III)。
4. Chemical Equations & the Mole Concept | 化学方程式与摩尔概念
QA exam. Always include state symbols: (s), (l), (g), (aq). Practise common reaction types – such as combustion of methane: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g), and acid‑base neutralisations.
SQA 考试中要求能够书写并配平化学方程式。务必标明状态符号：(s)、(l)、(g)、(aq)。多练习常见反应类型，例如甲烷燃烧：CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)，以及酸碱中和反应。
s in the formula. Master the triangle: moles = mass (g) / GFM (g/mol). A typical question: 'How many moles are there in 8.0 g of sulfur (Sᵣ = 32)?' Answer: 0.25 mol.
引入摩尔作为物质的量的 SI 单位。通过将化学式中所有原子的相对原子质量相加，计算出克式量 (GFM)。掌握摩尔三角关系：摩尔数 = 质量 (g) / GFM (g/mol)。典型例题：“8.0 g 硫中有多少摩尔？”(Sᵣ = 32) 答案：0.25 mol。
Work on reacting masses by following three steps: convert known mass to moles, use the balanced equation to find the mole ratio, then convert the unknown moles back to mass. This logical routine will handle most stoichiometric problems in National 5 Chemistry.
通过以下三步法计算反应质量：将已知质量换算为摩尔，利用配平方程式找出摩尔比，再将未知摩尔数换算为质量。这套逻辑流程能解决 National 5 化学中大多数化学计量问题。
5. Acids, Bases & Neutralisation | 酸、碱与中和反应
Define an acid as a substance that produces hydrogen ions (H⁺) in water, and a base as a substance that produces hydroxide ions (OH⁻). Learn the common laboratory acids: hydrochloric acid HCl(aq), sulfuric acid H₂SO₄(aq) and nitric acid HNO₃(aq), and bases such as sodium hydroxide NaOH(aq) and calcium hydroxide Ca(OH)₂(aq).
定义酸为在水溶液中产生氢离子 (H⁺) 的物质，碱为产生氢氧根离子 (OH⁻) 的物质。熟记常见的实验室酸：盐酸 HCl(aq)、硫酸 H₂SO₄(aq) 和硝酸 HNO₃(aq)，以及常见的碱，如氢氧化钠 NaOH(aq) 和氢氧化钙 Ca(OH)₂(aq)。
+ metal carbonate → salt + water + carbon dioxide. For instance, HCl + NaOH → NaCl + H₂O.
中和反应本质上就是 H⁺ + OH⁻ → H₂O。要能写出下列反应的配平方程式：酸 + 碱 → 盐 + 水；酸 + 金属氧化物 → 盐 + 水；酸 + 金属碳酸盐 → 盐 + 水 + 二氧化碳。例如，HCl + NaOH → NaCl + H₂O。
Name the salts formed: hydrochloric acid gives chlorides, sulfuric acid gives sulfates, nitric acid gives nitrates. This predictable pattern can help you write products quickly, even for unfamiliar reactions.
正确命名生成的盐：盐酸生成盐酸盐（氯化物），硫酸生成硫酸盐，硝酸生成硝酸盐。这种可预测的规律能帮助你在遇到陌生反应时快速写出产物。
6. The pH Scale, Indicators & Salt Preparation | pH 标度、指示剂与盐的制备
The pH scale runs from 0 to 14: values below 7 are acidic, 7 is neutral, and above 7 are alkaline. A strong acid completely dissociates in water, while a weak acid only partially dissociates. This distinction is key to understanding conductivity and reaction rate differences.
pH 标度范围为 0 到 14：小于 7 为酸性，等于 7 为中性，大于 7 为碱性。强酸在水中完全电离，而弱酸仅部分电离。这一区别对于理解导电性和反应速率的差异至关重要。
Know the main indicators: universal indicator (and pH paper) gives a full spectrum; litmus turns red in acid and blue in alkali; phenolphthalein changes from colourless to pink in alkali; methyl orange is red in acid and yellow in alkali. Choosing the right indicator is often required for titration questions.
熟悉主要指示剂：通用指示剂（和 pH 试纸）呈现全色域；石蕊在酸性中变红，在碱性中变蓝；酚酞在碱性中由无色变为粉红；甲基橙在酸性中为红色，在碱性中为黄色。在滴定问题中常常需要选择正确的指示剂。
For preparing a soluble salt, the titration‑crystallisation method is standard. Use a pipette to measure a known volume of alkali, add acid from a burette with a few drops of indicator, note the endpoint volume, then repeat without indicator. Finally, evaporate some water and leave to crystallise to obtain pure salt.
制备可溶盐的标准方法是滴定结晶法。用移液管取一定体积的碱液，从滴定管中逐滴加入酸，并加入几滴指示剂，记录终点体积，然后在不加指示剂的情况下重复实验。最后蒸发部分水，静置结晶，即可得到纯净的盐晶体。
7. Oxidation, Reduction & Electrochemistry | 氧化还原与电化学
s electrons and is reduced. In a displacement reaction such as Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s), zinc loses electrons (oxidised) and copper(II) ions gain electrons (reduced).
记住“失养得还”的对应英文口诀 OIL RIG：氧化即失电子，还原即得电子。能够鉴定氧化剂——得电子被还原的物质。在置换反应中，例如 Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s)，锌失去电子（被氧化），铜(II) 离子得到电子（被还原）。
ectrolyte. The further apart the metals are in the reactivity series, the greater the voltage produced. Be able to write ion‑electron half‑ u (reduction). Flow of electrons is from the more reactive metal to the less reactive one.
在简单电化学电池中，两种不同的金属被放入同一电解质中。金属在活动性顺序表中相距越远，产生的电压越大。要能书写离子-电子半反应式：Zn → Zn²⁺ + 2e⁻（氧化），Cu²⁺ + 2e⁻ → Cu（还原）。电子流动方向是从较活泼的金属到较不活泼的金属。
