1. The Structure of the Eduqas GCSE Chemistry Course | Eduqas GCSE 化学课程的结构
The Eduqas GCSE Chemistry qualification consists of two examined components and a practical assessment. The content is divided into broad topics that are covered across Year 10 and Year 11. In Year 10, you will typically study the foundational topics that build your understanding of particles, atomic structure, bonding, and the principles of chemical reactions.
Eduqas GCSE 化学资格由两个笔试单元和一项实验评估组成。课程内容分为若干大主题，分布在 Year 10 和 Year 11 的教学中。Year 10 通常会学习基础主题，帮助你建立对粒子、原子结构、化学键以及化学反应原理的理解。
Component 1: Concepts in Chemistry (written exam, 45% of the qualification) – covers the majority of the theory content, including atomic structure, bonding, the Periodic Table, quantitative chemistry, and organic chemistry.
组件 1：化学概念（笔试，占成绩的 45%）– 涵盖大部分理论知识，包括原子结构、化学键、元素周期表、定量化学和有机化学。
Component 2: Applications in Chemistry (written exam, 45% of the qualification) – focuses on the application of concepts to areas such as rates of reaction, energy changes, electrolysis, and chemical analysis.
组件 2：化学应用（笔试，占成绩的 45%）– 侧重于化学概念在反应速率、能量变化、电解和化学分析等领域的应用。
Practical Assessment (10%) – there is no separate practical exam; instead, the written papers include questions that test your understanding of prescribed practicals. You must carry out specified experiments and be able to describe methods, results, and analysis.
实验评估（占 10%）– 没有单独的动手操作考试，而是在笔试卷中包含考查你对规定实验理解的题目。你必须完成指定的实验，并能够描述实验方法、结果和分析。
This structure means that your practical skills are assessed alongside your theoretical knowledge. Year 10 typically covers around half of the required practicals and a significant portion of the Component 1 content.
这种结构意味着你的实验技能与理论知识将一同被评估。Year 10 通常涵盖大约一半的规定实验以及组件 1 中的大部分内容。
2. Key Topic 1 – Particles and States of Matter | 主题 1——粒子与物质的状态
The course begins with the particle model of matter, which is essential for explaining physical changes. You will learn about the arrangement, movement, and energy of particles in solids, liquids, and gases. This model helps you understand why substances change state when heated or cooled.
课程从物质的粒子模型开始，这对于解释物理变化至关重要。你将学习固体、液体和气体中粒子的排列、运动和能量。该模型帮助你理解为什么物质在加热或冷却时会发生状态变化。
Particles in a solid are closely packed in a regular arrangement and vibrate in fixed positions.
固体中的粒子紧密排列，有规则的结构，并在固定位置上振动。
In a liquid, particles are close together but can move past each other, taking the shape of the container.
液体中的粒子彼此接近，但可以相互滑动，呈现容器的形状。
Gas particles are far apart and move rapidly in all directions.
气体粒子相距很远，朝各个方向快速运动。
A key limitation of the particle model is that it assumes particles are solid spheres and does not account for intermolecular forces or the sizes of particles. However, it is useful for explaining diffusion and changes in pressure.
粒子模型的一个关键局限性是它假设粒子为实心球体，没有考虑到粒子间的分子间作用力或粒子的大小。然而，它在解释扩散和压力变化时非常实用。
3. Key Topic 2 – Atomic Structure and the Periodic Table | 主题 2——原子结构与元素周期表
Understanding the atom is fundamental. You will study the subatomic particles—protons, neutrons, and electrons—and learn how to use atomic number and mass number. This leads directly to the arrangement of electrons in shells (electron configuration) and how this determines an element’s position in the Periodic Table.
理解原子是化学的基础。你将学习亚原子粒子——质子、中子和电子——并学习如何使用原子序数和质量数。这直接引向电子的层排列（电子排布），以及它如何决定元素在周期表中的位置。
| Particle | Relative Charge | Relative Mass |
| Proton | +1 | 1 |
| Neutron | 0 | 1 |
| Electron | -1 | ≈ 0 (1/1836) |
The modern Periodic Table is arranged by increasing atomic (proton) number. Elements in the same group have the same number of outer electrons, resulting in similar chemical properties. You will also explore the evolution of the Periodic Table from early attempts by Newlands and Mendeleev.
现代元素周期表按原子序数（质子数）递增排列。同族元素具有相同的最外层电子数，因此化学性质相似。你还将探索周期表从纽兰兹和门捷列夫的早期尝试演变至今的历史。
4. Key Topic 3 – Chemical Bonding and Structure | 主题 3——化学键与结构
Three main types of bonding are covered: ionic, covalent, and metallic. You must be able to describe how each bond forms, draw diagrams, and explain the properties of the resulting structures. This topic links closely to the nature of elements—whether they are metals or non-metals.
课程涵盖三种主要的化学键类型：离子键、共价键和金属键。你必须能够描述每种键的形成方式，绘制示意图，并解释所形成的结构的性质。这个主题与元素的本质——它们是金属还是非金属——紧密相连。
Ionic bonding occurs between a metal and a non-metal, involving the transfer of electrons to form oppositely charged ions, which are held together by strong electrostatic forces. Ionic compounds have high melting points and conduct electricity when molten or in solution.
离子键发生在金属和非金属之间，通过电子转移形成带相反电荷的离子，这些离子由强静电力结合在一起。离子化合物具有高熔点，在熔融或溶解时能导电。
Covalent bonding is the sharing of electron pairs between non-metal atoms. Simple molecular substances have low melting points and do not conduct electricity, whereas giant covalent structures (like diamond and graphite) have very high melting points.
共价键是非金属原子之间共享电子对。简单分子物质具有低熔点且不导电，而巨型共价结构（如金刚石和石墨）则具有极高的熔点。
Metallic bonding involves a lattice of positive ions surrounded by a ‘sea’ of delocalised electrons. This explains why metals are malleable, ductile, and good conductors of heat and electricity.
金属键由正离子晶格被离域电子的“海洋”包围而成。这解释了为什么金属具有延展性、可锻性，并且是良好的导热和导电体。
Nanoparticles and their properties are also part of this topic, introducing students to the idea that properties can change at the nanoscale.
纳米粒子及其性质也是本主题的一部分，向学生介绍性质在纳米尺度上可能发生变化的概念。
5. Key Topic 4 – Quantitative Chemistry | 主题 4——定量化学
This topic introduces the mathematics of chemistry. You will learn to calculate relative formula masses, use the mole concept, and determine empirical and molecular formulae. Being able to balance equations and calculate reacting masses is a central skill.
本主题介绍化学中的数学运算。你将学习计算相对式量、运用摩尔概念，并确定经验式和分子式。能够配平化学方程式并计算反应质量是一项核心技能。
Number of moles = mass (g) ÷ molar mass (g/mol)
摩尔数 = 质量(g) ÷ 摩尔质量(g/mol)
You will also study percentage yield and atom economy, which are key concepts in industrial chemistry for assessing efficiency and minimizing waste. Calculations involving concentrations of solutions (in g/dm³ or mol/dm³) are also introduced, often linked to titration procedures in the practicals.
你还将学习产率百分比和原子经济性，这是工业化学中评估效率和尽量减少废物的关键概念。涉及溶液浓度的计算（以 g/dm³ 或 mol/dm³ 表示）也将被引入，通常会与实验操作中的滴定程序联系起来。
6. Key Topic 5 – Chemical Reactions and Energy Changes | 主题 5——化学反应与能量变化
In Year 10, you begin to study the energy changes that accompany chemical reactions. Exothermic reactions (such as combustion and neutralisation) transfer energy to the surroundings, raising the temperature. Endothermic reactions (such as thermal decomposition) absorb energy, causing a temperature drop.
在 Year 10，你开始学习伴随化学反应的能量变化。放热反应（如燃烧和中和）向周围环境传递能量，使温度升高。吸热反应（如热分解）吸收能量，导致温度下降。
Reaction profiles show the energy of reactants and products, as well as the activation energy barrier.
反应曲线显示了反应物和产物的能量，以及活化能势垒。
Bond breaking is endothermic, while bond making is exothermic. By comparing the energy required to break bonds in reactants with the energy released when making bonds in products, you can calculate the overall enthalpy change.
断裂化学键是吸热过程，形成化学键是放热过程。通过比较反应物断键所需的能量与生成物成键释放的能量，就可以计算总焓变。
This topic also includes an introduction to cells and batteries, linking chemical reactions to electrical energy, and fuel cells as a clean energy technology.
本主题还简要介绍了电池和化学电池，将化学反应与电能联系起来，并介绍了作为一种清洁能源技术的燃料电池。
7. Key Topic 6 – Rates of Reaction and Equilibrium | 主题 6——反应速率与平衡
Understanding how to measure and control the rate of a reaction is a practical and theoretical skill. You will learn to calculate mean rate of reaction from graphs of volume of gas produced or mass lost over time. Factors affecting rate include concentration, pressure, temperature, surface area, and the presence of a catalyst.
理解和控制反应速率是一项实践与理论并重的技能。你将学习从气体产生体积或质量随时间变化的图表中计算平均反应速率。影响反应速率的因素包括浓度、压力（对气体）、温度、表面积以及催化剂的存在。
Collision theory is used to explain why these factors alter the rate: reactions occur when particles collide with sufficient energy (the activation energy) and in the correct orientation.
碰撞理论用于解释这些因素为何会改变反应速率：当粒子以足够的能量（达到活化能）和正确的方向发生碰撞时，反应才会发生。
Dynamic equilibrium is introduced for reversible reactions. When a reaction reaches equilibrium in a closed system, the rates of forward and reverse reactions are equal. Le Chatelier’s Principle helps you predict how the equilibrium position shifts in response to changes in temperature, pressure, or concentration.
可逆反应中引入了动态平衡的概念。当反应在封闭系统中达到平衡时，正逆反应速率相等。勒夏特列原理有助于预测平衡位置如何随温度、压强或浓度的变化而移动。
8. Key Topic 7 – Organic Chemistry: Fuels and Feedstocks | 主题 7——有机化学：燃料和原料
Year 10 covers the basics of organic chemistry, focusing on hydrocarbons. Crude oil is a mixture of alkanes, which are separated by fractional distillation based on boiling points. You need to know the first four alkanes—methane (CH₄), ethane (C₂H₆), propane (C₃H₈), and butane (C₄H₁₀)—and their general formula CₙH₂ₙ₊₂.
Year 10 涵盖有机化学的基础知识，重点关注碳氢化合物。原油是一种烷烃混合物，通过分馏工艺根据沸点差异进行分离。你需要了解前四种烷烃——甲烷(CH₄)、乙烷(C₂H₆)、丙烷(C₃H₈)和丁烷(C₄H₁₀)——以及它们的通式 CₙH₂ₙ₊₂。
Complete combustion of hydrocarbons produces carbon dioxide and water, while incomplete combustion can result in toxic carbon monoxide and soot.
碳氢化合物的完全燃烧生成二氧化碳和水，而 不完全燃烧则可能产生有毒的一氧化碳和碳烟。
d) are introduced as more reactive than alkanes. Ethene, propene, and butene can be used to make polymers.
烯烃（含有 C=C 双键）被介绍为比烷烃更活泼。乙烯、丙烯和丁烯可用于制造聚合物。
The addition polymerisation reaction and the structure of polymers such as poly(ethene) and poly(propene) are covered, linking back to bonding and structure.
主题包含加成聚合反应以及聚（乙烯）和聚（丙烯）等聚合物的结构，并且回顾化学键与结构的内容。
