课程大纲分为所有考生必学的核心部分（Core）和针对高分段（A*–C）的扩展部分（Supplement）。主题划分为三大领域：化学原理、物理化学，以及无机与有机化学。所有考生需参加三个部分的考试。
| 组件 | 核心考生 (Core) | 扩展考生 (Extended) | 说明 |
|---|---|---|---|
| 选择题 | Paper 1 (40题, 45分钟) | Paper 2 (40题, 45分钟) | 占30% |
| 理论题 | Paper 3 (80分, 1小时15分钟) | Paper 4 (80分, 1小时15分钟) | 占50% |
| 实验/替代实验 | Paper 5 (实验操作, 1小时15分钟) 或 Paper 6 (替代实验, 1小时) | Paper 5 或 Paper 6 | 占20% |
Core content covers the essentials, while Supplement extends into more quantitative and conceptual depth, such as mole calculations, electrolysis predictions, and organic reaction pathways. A clear understanding of which tier you are entering is vital from the start.
核心内容覆盖基础知识，扩展部分则深入定量计算与概念理解，例如摩尔运算、电解产物预测和有机反应路径。从一开始就明确自己报考的级别至关重要。
2. States of Matter and the Kinetic Particle Model | 物质状态与粒子动理论模型
The three states of matter are described by the arrangement, movement, and energy of particles. Solids have fixed shapes and volumes because particles are closely packed in a regular arrangement, vibrating in place. Liquids have fixed volumes but take the shape of their container, while gases expand to fill any volume due to rapid, random particle motion.
物质的三态由粒子的排列、运动和能量决定。固体有固定的形状和体积，因为粒子紧密有序排列，只在固定位置振动。液体有固定体积但形状随容器改变，气体则因粒子快速随机运动而充满整个容器。
Changes of state—melting, boiling, freezing, condensation, and sublimation—occur at constant temperatures for pure substances. Diffusion provides evidence for particle motion: lighter gas molecules diffuse faster (Graham's Law). The rate of diffusion increases with temperature and decreases with increasing molecular mass.
纯净物在熔化、沸腾、凝固、冷凝和升华过程中温度保持恒定。扩散为粒子运动提供了证据：较轻的气体分子扩散更快（格雷姆定律）。扩散速率随温度升高而加快，随分子质量增大而减慢。
Rate of diffusion ∝ 1 / √molar mass
3. Atomic Structure and the Periodic Table | 原子结构与元素周期表
Atoms consist of protons (relative charge +1, mass 1), neutrons (0, mass 1), and electrons (–1, mass 1/1836). The atomic number (Z) equals the number of protons and defines the element; mass number (A) equals protons+neutrons. Isotopes have the same Z but different numbers of neutrons, exhibiting identical chemical properties but different physical properties.
原子由质子（相对电荷+1，质量1）、中子（0，质量1）和电子（–1，质量1/1836）组成。原子序数（Z）等于质子数，决定了元素的种类；质量数（A）等于质子数+中子数。同位素质子数相同但中子数不同，化学性质相同而物理性质有异。
Electrons are arranged in shells (2,8,8,2 for first 20 elements). The electronic configuration determines chemical reactivity and bonding. The Periodic Table arranges elements in order of increasing atomic number, with groups (columns) showing similar chemical properties due to the same number of outer-shell electrons. Periods (rows) reflect the filling of electron shells.
电子按壳层排布（前20号元素为2,8,8,2）。电子排布决定了化学活泼性和成键方式。周期表按原子序数递增排列，族（纵列）因最外层电子数相同而具有相似的化学性质。周期（横行）反映了电子壳层的填充。
Transition metals, placed between Group 2 and Group 3, exhibit high melting points, form coloured compounds, and often act as catalysts. Group 1 elements (alkali metals) are highly reactive, while Group 7 (halogens) reactivity decreases down the group. Group 0 (noble gases) are inert due to full outer shells.
过渡金属位于第2族与第3族之间，熔点高、能形成有色化合物，常作为催化剂。第1族（碱金属）非常活泼，第7族（卤素）活泼性从上到下递减。第0族（稀有气体）因最外层全满而性质稳定。
4. Chemical Bonding: Ionic, Covalent, and Metallic | 化学键：离子键、共价键与金属键
Ionic bonding involves the transfer of electrons from a metal to a non-metal, forming oppositely charged ions held together by strong electrostatic forces. Giant ionic lattices have high melting and boiling points, conduct electricity when molten or dissolved, and are often soluble in water. The formula unit represents the simplest ratio of ions, e.g., NaCl, MgO, Al₂O₃.
离子键是金属向非金属转移电子，形成带相反电荷的离子，依靠强大静电引力结合。巨型离子晶体熔沸点高，在熔融或水溶液状态下导电，通常可溶于水。化学式表示最简离子比，如NaCl、MgO、Al₂O₃。
Covalent bonding occurs when atoms share pairs of electrons to achieve a full outer shell. Simple molecular substances (e.g., H₂O, CO₂, NH₃) have low melting and boiling points and do not conduct electricity. Giant covalent structures (diamond, graphite, SiO₂) have very high melting points. Diamond is hard, while graphite conducts electricity and acts as a lubricant due to its layered structure with delocalised electrons.
共价键是原子通过共用电子对以达到最外层满壳层。简单分子物质（如H₂O、CO₂、NH₃）熔沸点低，不导电。巨型共价结构（金刚石、石墨、SiO₂）熔沸点极高。金刚石极硬，石墨因层状结构与离域电子可以导电并用作润滑剂。
Metallic bonding is described as a lattice of positive ions in a 'sea' of delocalised electrons. This structure explains high melting points, malleability, ductility, and electrical conductivity. Alloys are mixtures of metals with other elements, disrupting the regular lattice and making them harder.
金属键被描述为阳离子浸在“离域电子海”中的晶格。该结构解释了金属的高熔点、延展性和导电性。合金是金属与其他元素的混合物，打乱了规则的晶格，使硬度增大。
5. Stoichiometry and the Mole Concept | 化学计量学与摩尔概念
es (Avogadro constant). Molar mass (Mᵣ for elements, formula mass for compounds) is the mass of one mole in grams. Key formulae link mass, moles, and relative atomic/molecular mass.
摩尔是物质的量的单位，包含6.02 × 10²³个粒子（阿伏伽德罗常数）。摩尔质量（元素的Mᵣ，化合物的式量）是一摩尔物质的质量（克）。关键公式将质量、摩尔数和相对原子/分子质量联系起来。
n = m / Mᵣ
Empirical formula is the simplest whole number ratio of atoms; molecular formula is the actual number of atoms in a molecule. Percentage composition by mass, reacting masses, and limiting reactants are fundamental quantitative skills. For gases, at room temperature and pressure (r.t.p.), one mole occupies 24 dm³.
实验式是原子最简整数比；分子式是一个分子中实际的原子数目。质量百分比、反应质量和限制反应物是基本的定量技能。对于气体，在室温常压下（r.t.p.），一摩尔体积约为24 dm³。
ld and percentage purity are practical applications, with percentage yield = (actual yield / theoretical yield) × 100%.
浓度计算涉及mol/dm³和质量浓度g/dm³。滴定计算常用公式：c₁V₁ / n₁ = c₂V₂ / n₂。产率和百分纯度是实际应用，产率百分数 = （实际产量 / 理论产量）× 100%。
6. Electrochemistry and Redox | 电化学与氧化还原反应
Oxidation is loss of electrons (OIL), reduction is gain of electrons (RIG). Redox reactions are identifiable through changes in oxidation states. Electrolysis involves the decomposition of an electrolyte by direct current. In molten ionic compounds, cations migrate to the cathode and gain electrons (reduction), anions migrate to the anode and lose electrons (oxidation).
氧化是失电子（OIL），还原是得电子（RIG）。氧化还原反应可通过氧化态的变化识别。电解指电解质在直流电作用下分解。在熔融离子化合物中，阳离子移向阴极得电子（还原），阴离子移向阳极失电子（氧化）。
For aqueous solutions, discharge at electrodes follows a reactivity series. At the cathode, less reactive metal ions or H⁺ (from water) are discharged. At the anode, OH⁻ ions (from water) are discharged unless a concentrated halide is present. Key industrial processes include extraction of aluminium (Al₂O₃ dissolved in cryolite) and purification of copper.
在水溶液中，电极放电遵循金属活动性顺序。阴极处，较不活泼的金属离子或水中的H⁺优先放电。阳极处，除非有浓卤化物存在，否则水中的OH⁻放电。重要的工业应用包括电解铝（Al₂O₃溶于冰晶石）和精炼铜。
Simple cells use two different metals in an electrolyte to produce electricity via displacement reactions. Hydrogen fuel cells combine H₂ and O₂ to generate electricity, with water as the only product, offering a clean energy alternative.
简单电池利用两种金属在电解质中的置换反应产生电流。氢氧燃料电池使H₂与O₂反应发电，仅产生水，是一种清洁能源替代方案。
7. Chemical Energetics and Reversible Reactions | 化学能量学与可逆反应
Exothermic reactions release heat to the surroundings (ΔH negative), observed as a temperature rise (e.g., combustion, neutralisation). Endothermic reactions absorb heat (ΔH positive), causing cooling (e.g., photosynthesis, thermal decomposition). Energy level diagrams show the relative enthalpy of reactants and products, with activation energy (Eₐ) as the minimum energy needed for a reaction to occur.
放热反应向环境释放热量（ΔH为负），表现为温度升高（如燃烧、中和反应）。吸热反应从环境吸热（ΔH为正），导致降温（如光合作用、热分解）。能级图显示反应物与产物的相对焓值，活化能（Eₐ）是发生反应所需的最低能量。
d making is exothermic. Simple calorimetry experiments measure enthalpy changes using ΔH = – is moles. Improving accuracy involves insulating the container and repeating measurements.
断键吸热，成键放热。简易量热实验通过ΔH = –mcΔT / n计算焓变，其中m为溶液质量，c为比热容，n为摩尔数。提高准确度可以通过保温容器和重复测定实现。
Reversible reactions reach a state of dynamic equilibrium when the rates of forward and reverse reactions are equal. Equilibrium can be shifted by changing temperature, pressure (for gases), or concentration, as predicted by Le Chatelier's Principle. In the Haber Process (N₂ + 3H₂ ⇌ 2NH₃), high pressure favours the forward reaction, while a compromise temperature of 450 °C maximises yield and rate.
可逆反应在正逆反应速率相等时达到动态平衡。根据勒夏特列原理，改变温度、压强（针对气体）或浓度会使平衡发生移动。在哈伯法合成氨（N₂ + 3H₂ ⇌ 2NH₃）中，高压有利于正反应，而采用450 °C的折中温度是为了兼顾产率和速率。
8. Acids, Bases, and the Chemistry of Salts | 酸、碱与盐的化学
H₂SO₄, and HNO₃. Alkalis are soluble bases that release OH⁻ ions in water. The pH scale (0– indicator or probes. Neutralisation produces a salt and water: Acid + Base → Salt + Water.
酸是质子（H⁺）给予体，碱是质子接受体。常见酸有HCl、H₂SO₄和HNO₃。碱是能溶于水并释放OH⁻的物质。pH标度（0–14）用万能指示剂或探头测量酸碱度。中和反应生成盐和水：酸 + 碱 → 盐 + 水。
Making soluble salts can involve reacting an acid with a metal, metal oxide, metal hydroxide, or metal carbonate. Crystals are obtained by filtration, evaporation, and crystallisation. Solubility rules help predict whether a precipitate will form when two solutions are mixed, useful for qualitative analysis.
制备可溶性盐可通过酸与金属、金属氧化物、金属氢氧化物或金属碳酸盐的反应实现。经过滤、蒸发和结晶可得晶体。溶解性规律有助于预测两种溶液混合时是否形成沉淀，这在定性分析中十分有用。
iate in water (e.g., HCl → H⁺ + Cl⁻), while weak acids partially dissociate (e.g., CH₃COOH ⇌ icators are a core quantitative skill for determining concentrations of unknown solutions.
强酸在水中完全电离（如HCl → H⁺ + Cl⁻），弱酸则部分电离（如CH₃COOH ⇌ H⁺ + CH₃COO⁻）。这解释了相同浓度下导电性、反应速率和pH的差异。使用指示剂的滴定法是测定未知溶液浓度的核心定量技能。
9. Introduction to Organic Chemistry | 有机化学基础
ns, showing isomerism from butane (C₄H₁₀) onwards. Their reactions include combustion and substitution with halogens (e.g., CH₄ + Cl₂ → CH₃Cl + HCl, in UV light).
有机化学研究含碳化合物，不包括碳酸盐和氧化物。烷烃（CₙH₂ₙ₊₂）是饱和烃，从丁烷（C₄H₁₀）开始出现同分异构。它们的反应包括燃烧与卤素的取代反应（如CH₄ + Cl₂ → CH₃Cl + HCl，需紫外光）。
bond, making them unsaturated. They undergo addition reactions: with hydrogen (hydrogenation), water (hydration to produce alcohols), and halogens (bromine water test turns from orange to colourless). The addition polymerisation of ethene produces poly(ethene), widely used in plastics.
烯烃（CₙH₂ₙ）含有C=C双键，属于不饱和烃。它们发生加成反应：与氢气（氢化）、与水（水合制醇）、与卤素（溴水试验从橙色变为无色）。乙烯的加成聚合生成聚乙烯，广泛用于塑料。
+ 2CO₂) or hydration of ethene. Ethanol undergoes combustion, oxidation to ethanoic acid, and esterification with carboxylic acids. Carboxylic acids (e.g., CH₃COOH) are weak acids; esters have sweet smells and are used in perfumes.
醇（CₙH₂ₙ₊₁OH）可通过发酵（C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂）或乙烯水合制得。乙醇能燃烧，可被氧化为乙酸，并与羧酸发生酯化。羧酸（如CH₃COOH）是弱酸；酯有香甜气味，用于香水。
10. Experimental Skills and the Alternative to Practical Paper | 实验技能与替代实验考试
Practical skills are assessed either through the Practical Test (Paper 5) or the written Alternative to Practical (Paper 6). The latter requires interpreting experimental data, identifying apparatus errors, drawing line graphs, and designing investigations. Common techniques include titration, filtration, distillation, chromatography, and measuring rates by gas volume or loss of mass.
实验技能通过实际操作考试（Paper 5）或替代实验笔试（Paper 6）评估。后者要求解读实验数据、识别仪器误差、绘制线图并设计探究实验。常见技术包括滴定、过滤、蒸馏、色谱法，以及通过气体体积或质量损失测量反应速率。
For enthalpy change experiments, students must recognise sources of heat loss and suggest improvements. For separation techniques, they should be able to label apparatus and choose the appropriate method (simple distillation, fractional distillation, crystallisation, or paper chromatography) based on substance properties. Understanding the use of locating agents and Rf values in chromatography is frequently examined.
在焓变实验中，学生需识别热量散失的来源并提出改进方案。对于分离技术，须能标注仪器，并根据物质性质选择合适的方法（简单蒸馏、分馏、结晶或纸色谱）。理解色谱中显色剂的使用和Rf值的计算常出现在考题中。
Safe handling of chemicals, accurate measurement, and recording observations in a clear table are core expectations. In Paper 6, always pay attention to the number of significant figures, appropriate graph scales, and drawing a best-fit line.
安全处理化学品、准确测量并以清晰的表格记录观察结果是基本素养。在Paper 6中，应始终注意有效数字位数、合适的坐标轴比例，并绘制最佳拟合线。
11. Revision Strategies and Exam Technique | 复习策略与考试技巧
Active recall—writing down everything you know about a topic before checking notes—strengthens long-term memory. Pair this with spaced repetition and past paper practice. For Cambridge IGCSE Chemistry, past papers are essential to understand command words: 'Define', 'Explain', 'Describe', 'Predict', and 'Calculate' each require distinct approaches.
主动回忆法——在查阅笔记之前写下你对一个主题所知的一切——能强化长期记忆。配合间隔重复和历年真题训练效果更佳。在剑桥IGCSE化学中，真题对理解指令词至关重要：“定义”、“解释”、“描述”、“预测”、“计算”等各有不同的答题要求。
In Paper 4 (Extended Theory), significant marks are allocated to chemical equations with state symbols, dot-and-cross diagrams, and explaining trends with ideas about structure and bonding. Always show working for mole calculations to gain partial credit if the final answer is incorrect. Time management is key: allocate roughly one minute per mark.
在Paper 4（扩展理论）中，大量分值分配给带状态符号的化学方程式、点叉图，以及基于结构与键合的原理解释趋势。摩尔计算必须展示步骤，即使最终答案错误也能获得部分分数。时间管理至关重要：大约每分一分钟。
For the multiple-choice papers (1 or 2), eliminate obviously wrong answers, and watch out for common distractors like confusing isotopes with different elements, or forgetting that ionic compounds do not contain discrete molecules. Revisit mechanisms for organic addition and substitution to avoid mixing them up.
对于选择题试卷（Paper 1或2），要排除明显错误的选项，并注意常见干扰项，比如将同位素与不同元素混淆，或忘记离子化合物并不含独立分子。复习有机加成反应与取代反应的机理，避免混淆。
12. Linking Syllabus Topics to Real-World Context | 课程主题与现实世界的连接
Understanding how chemical principles apply in everyday life deepens comprehension and aids memory. The extraction of aluminium by electrolysis is linked to recycling and conservation of energy. The Haber Process for ammonia production feeds into fertiliser manufacture, supporting global agriculture. Polymer chemistry relates to plastic pollution and the development of bioplastics.
理解化学原理在生活中的应用能深化理解并帮助记忆。电解炼铝与能源回收和节能减排密切相关。哈伯法合成氨关系到化肥生产，支撑全球农业。高分子化学与塑料污染及生物塑料的开发紧密相连。
Climate change and fuel cells connect with electrochemistry and energetics. The carbon cycle, photosynthesis, and combustion reactions illustrate the balance of O₂ and CO₂. Acid rain (from SO₂ and NOₓ) links to acid-base chemistry and redox reactions. Such connections are frequently explored in examination questions.
气候变化和燃料电池与电化学及能量学相关联。碳循环、光合作用与燃烧反应展现了O₂与CO₂的平衡。酸雨（由SO₂和NOₓ引起）联系到酸碱化学与氧化还原反应。这些联系经常出现在考题中。
