📚 Mastering the AQA AS Chemistry Insert (Jun 22) | 掌握AQA AS化学试卷插页（2022年6月）

The AQA AS Chemistry Insert for June 2022 (Paper 1) is more than just a reference sheet — it is a carefully curated toolkit of data designed to support your exam performance. Knowing exactly what is on the insert, and how to use it efficiently, can save you valuable time and help you avoid careless errors.

2022年6月AQA AS化学试卷一（Paper 1）的插页不仅仅是一张参考资料——它是一份精心整理的数据工具包，旨在为你的考试表现提供支持。准确了解插页上有什么、以及如何高效使用它，可以为你在考试中节省宝贵时间，并帮助你避免粗心错误。

1. What Is the Insert and Why Does It Matter? | 插页是什么，为什么它很重要？

The AQA AS Chemistry Insert is a double-sided document provided with your question paper. For the June 2022 Paper 1 (7404/1), the insert contains the Periodic Table, along with selected physical chemistry data such as ionisation energies, bond enthalpy values, and standard electrode potentials where relevant.

AQA AS化学插页是一份随试卷提供的双面文件。针对2022年6月试卷一（7404/1），插页包含元素周期表，以及选定的物理化学数据，如电离能、键焓值和相关的标准电极电位。

Central resource: All the data you need is given at the start — you do not need to memorise every value.
核心资源：所有你需要的数据都在卷首给出——你不需要记住每一个数值。
Timing advantage: Fluency in locating a value quickly means more time for thinking and calculations.
时间优势：快速定位数值的熟练度意味着你有更多时间进行思考和计算。
Error reduction: Using correct relative atomic masses and ionisation energies prevents silly mistakes.
减少错误：使用正确的相对原子质量和电离能可以防止低级错误。

2. The Periodic Table on the Insert | 插页上的元素周期表

The Periodic Table printed on the insert is the standard AQA version. Each element is displayed with its atomic number (proton number), symbol, and relative atomic mass. For hydrogen, for example, you will see atomic number 1 and relative atomic mass 1.008 — note that this is not rounded to 1 in all calculations.

插页上印制的元素周期表是AQA标准版本。每个元素都显示其原子序数（质子数）、符号和相对原子质量。例如氢元素，你会看到原子序数为1，相对原子质量为1.008——请注意，并非所有计算都可以将其四舍五入为1。

The key columns of the AQA table include the Group numbers (1 to 0, with Groups 1, 2 and 3 clearly marked for oxidation states) and the Period numbers on the left-hand side. The lanthanides and actinides are placed below the main body, as is conventional.

AQA元素周期表的关键列包括族号（1到0，其中第1、2和3族明确标出以用于氧化态判断）以及左侧的周期号。镧系和锕系元素按惯例放置在主表下方。

Periodic Table key data: Z = proton number, A_r = relative atomic mass

周期表关键数据：Z = 质子数，Aᵣ = 相对原子质量

3. Relative Atomic Mass: Precision Matters | 相对原子质量：精确度很重要

On the AQA insert, relative atomic masses (A_r) are given to three decimal places for most elements. For example, chlorine is listed as 35.45 and copper as 63.55. This precision allows you to perform mole calculations directly from the data provided.

在AQA插页上，大多数元素的相对原子质量（Aᵣ）精确到三位小数。例如，氯为35.45，铜为63.55。这样的精确度使你能够直接使用所提供的数据进行摩尔计算。

Don’t round unless asked: Use the exact A_r from the insert in your working.
不要随意取整：在计算中使用插页上精确的Aᵣ值。
Watch for isotopes: Relative atomic mass already accounts for isotopic abundance.
注意同位素：相对原子质量已经考虑了同位素丰度。
Example: n(Cl₂) = mass ÷ (2 × 35.45) = mass ÷ 70.90.
示例：n(Cl₂) = 质量 ÷ (2 × 35.45) = 质量 ÷ 70.90。

When calculating empirical formulae or reacting masses, always copy the Aᵣ value exactly. A common mistake is using 35.5 for chlorine; the insert says 35.45, so final answers should reflect that precision (typically rounded to 1 or 2 decimal places in the answer).

在计算经验式或反应质量时，始终精确抄写Aᵣ值。一个常见错误是使用氯的35.5；插页上写的是35.45，因此最终答案应反映该精确度（通常在答案中四舍五入到1或2位小数）。

4. First Ionisation Energy Data | 第一电离能数据

The insert provides first ionisation energies for the elements. These values are essential for explaining periodic trends, predicting reactions, and interpreting successive ionisation energy data.

插页提供了各元素的第一电离能。这些数值对于解释周期趋势、预测反应以及解读逐级电离能数据至关重要。

IE₁ trend across Period 3: Na (496) < Mg (738) < Al (578) < Si (786) < P (1012) < S (1000) < Cl (1251) < Ar (1521) kJ mol⁻¹

第3周期IE₁趋势：Na (496) < Mg (738) < Al (578) < Si (786) < P (1012) < S (1000) < Cl (1251) < Ar (1521) kJ mol⁻¹

General trend: IE₁ increases across a period due to increasing nuclear charge and decreasing atomic radius.
一般趋势：同一周期中，由于核电荷增加和原子半径减小，IE₁增大。
Drop from Mg to Al: The 3p electron in Al is at a higher energy, more shielded than the 3s electron in Mg.
Mg到Al的下降：Al中的3p电子处于更高能级，比Mg中的3s电子受到更多屏蔽。
Drop from P to S: The paired 3p electron in S experiences electron–electron repulsion.
P到S的下降：S中成对的3p电子经受电子之间的排斥作用。

In the June 2022 exam, you may be asked to explain these dips without numerically quoting the exact values — but having the values visible on the insert helps you confirm that the trend is indeed what you think it is.

在2022年6月的考试中，你可能会被要求解释这些下降趋势而无需精确引用数值——但插页上可见的数值能帮助你确认趋势确实如你所想。

5. Successive Ionisation Energies | 逐级电离能

The insert may also include data for successive ionisation energies across selected elements. These are crucial for deducing the number of outer-shell electrons and the group of an element.

插页可能还包含选定元素的逐级电离能数据。这些数据对于推断外层电子数量和元素的族别至关重要。

Consider an element with successive ionisation energies: 590, 1145, 4912, 6491, 8153 kJ mol⁻¹. The large jump between the second and third IE values (1145 → 4912) indicates that the element has two electrons in its outer shell — it belongs to Group 2.

考虑某元素的逐级电离能：590、1145、4912、6491、8153 kJ mol⁻¹。第二和第三电离能之间的大幅跃升（1145 → 4912）表明该元素外层有2个电子——它属于第2族。

Key rule: a sharp increase in IEₙ₊₁ vs IEₙ means the (n+1)th electron is removed from a new, inner shell.

关键规则：IEₙ₊₁相比IEₙ的急剧增加意味着第(n+1)个电子是从新的内壳层中移除的。

6. Atomic Radius and Electronegativity | 原子半径和电负性

While atomic radii and electronegativity values are not always listed in table form on the insert, the periodic table itself, together with ionisation energy data, allows you to infer these trends with confidence.

虽然原子半径和电负性数值并不总是以表格形式列在插页上，但元素周期表本身结合电离能数据，使你有信心推断出这些趋势。

Across a period: Atomic radius decreases because the increased nuclear charge pulls electrons closer.
同一周期：原子半径减小，因为核电荷增加将电子拉得更近。
Down a group: Atomic radius increases due to additional shells.
同一族中：由于电子壳层增加，原子半径增大。
Electronegativity: Increases across a period and decreases down a group.
电负性：同一周期增大，同一族减小。

In questions about bonding type, the difference in electronegativity between two elements (obtained from the periodic table position) determines whether the bond is ionic, polar covalent, or non-polar covalent.

在关于键合类型的题目中，两个元素之间的电负性差异（通过其在周期表中的位置获得）决定了键是离子键、极性共价键还是非极性共价键。

7. Bond Enthalpy Data on the Insert | 插页上的键焓数据

The insert includes a table of mean bond enthalpy values. These are essential for calculating enthalpy changes of reaction using the bond-breaking and bond-forming method.

插页包含平均键焓值表。这些数值对于使用断键和成键方法计算反应焓变至关重要。

ΔH = Σ(bonds broken) − Σ(bonds formed)

ΔH = Σ(断裂键能) − Σ(形成键能)

Typical values you might see: C–H: 412 kJ mol⁻¹, C–C: 348 kJ mol⁻¹, C=C: 612 kJ mol⁻¹, O=O: 496 kJ mol⁻¹, O–H: 463 kJ mol⁻¹. These are average bond enthalpies — they differ slightly from exact bond dissociation energies because they are averaged over different molecular environments.

你可能会看到的典型数值：C–H：412 kJ mol⁻¹，C–C：348 kJ mol⁻¹，C=C：612 kJ mol⁻¹，O=O：496 kJ mol⁻¹，O–H：463 kJ mol⁻¹。这些是平均键焓——它们与精确键解离能略有不同，因为它们是不同分子环境中取平均的结果。

Bond breaking is endothermic: Energy is absorbed (positive contribution).
断键是吸热的：能量被吸收（正贡献）。
Bond forming is exothermic: Energy is released (negative contribution).
成键是放热的：能量被释放（负贡献）。
Always draw a Hess diagram or write out the equation to avoid sign errors.
始终绘制赫斯图或写出方程式以避免符号错误。

8. Using the Insert for Hess’s Law Calculations | 使用插页进行赫斯定律计算

In the AS Paper 1 exam, Hess’s Law questions often appear alongside enthalpy of formation or combustion data. While the insert does not list enthalpies of formation, it does provide the bond enthalpy data needed for indirect calculation.

在AS试卷一的考试中，赫斯定律题目常与生成焓或燃烧焓数据一起出现。虽然插页未列出生成焓，但它确实提供了间接计算所需的键焓数据。

You are expected to construct a Hess cycle linking reactants and products via their elements. Using bond enthalpy data from the insert, you can find the enthalpy change of reaction for any gaseous reaction.

你应能够构建一个赫斯循环，将反应物和产物通过其元素连接起来。利用插页中的键焓数据，你可以计算出任何气相反应的焓变。

ΔH_r = ΔH_atomisation(reactants) + Σ bond enthalpies − ΔH_atomisation(products)

ΔH_r = ΔH原子化(反应物) + Σ键焓 − ΔH原子化(产物)

9. Standard Conditions and Data Interpretation | 标准状况和数据解读

All data on the insert is given at standard conditions: 298 K (25 °C) and 100 kPa. These are the conditions used for ΔH° values, ionisation energies, and electrode potentials.

插页上的所有数据都是在标准状况下给出的：298 K（25 °C）和100 kPa。这些是用于ΔH°值、电离能和电极电位的标准条件。

Do not confuse: Ionisation energies are always quoted as gaseous atoms losing electrons to form gaseous ions.
不要混淆：电离能总是以气态原子失去电子形成气态离子来表述。
First vs molar: Remember that ionisation energies are per mole of atoms or per atom depending on context — the insert uses kJ mol⁻¹.
第一电离能 vs 摩尔：记住电离能根据上下文是每摩尔原子或每个原子——插页使用kJ mol⁻¹。
State symbols matter: The insert data assumes specific states; always check state symbols in the question.
状态符号很重要：插页数据假设了特定状态；始终检查题目中的状态符号。

In the June 2022 paper, candidates who failed to specify “gaseous” in defining first ionisation energy lost marks. Make sure your definitions are precise and complete.

在2022年6月的试卷中，未能在定义第一电离能时指明”气态”的考生丢分了。确保你的定义精确且完整。

10. Common Pitfalls and How to Avoid Them | 常见陷阱及如何避免

Many students lose marks not because they lack knowledge but because they misuse the insert data. Let’s examine the most frequent pitfalls seen in the June 2022 session.

许多学生丢分不是因为缺乏知识，而是因为误用了插页数据。让我们审视2022年6月考试中最常见的陷阱。

Pitfall \| 陷阱	Consequence \| 后果	Solution \| 解决方案
Rounding Aᵣ too early	Inaccurate final answer	Carry full precision through calculations
过早四舍五入Aᵣ	最终答案不准确	在计算过程中保持完整精度
Ignoring state symbols in IE definition	Definition not credited	Always write ‘gaseous atom’
忽略电离能定义中的状态符号	定义不得分	始终写出”气态原子”
Using wrong bond enthalpy for a double bond	ΔH error	Match bond order carefully
对双键使用错误的键焓值	ΔH计算错误	仔细匹配键级
