Periodic Table AQA A Level – Data Booklet Contents Guide

The AQA A-Level Chemistry Data Booklet serves as an essential reference material provided alongside examination papers for specification 7405. This resource eliminates the need for students to memorise extensive spectroscopic data and physical constants, allowing them to focus on applying their understanding during Paper 1 and Paper 2 assessments. Understanding what this booklet contains—and how it differs from earlier specifications or alternative exam boards—can significantly improve revision efficiency and examination confidence.

The data booklet includes a complete periodic table showing all elements from hydrogen through the actinides, along with specialised tables for infrared absorption data, proton nuclear magnetic resonance chemical shifts, and carbon-13 nuclear magnetic resonance chemical shifts. Students also receive structures of biologically relevant molecules such as phosphates, sugars, nucleobases, amino acids, and the heme group. These resources are particularly valuable for organic synthesis and spectral interpretation questions that appear throughout the linear assessment.

What is Included in the AQA A-Level Chemistry Data Booklet?

The AQA A-Level Chemistry Data Booklet functions as an official examination insert, distributed with live papers for specification 7405. Its primary purpose is to provide students with reference data that would otherwise require memorisation, allowing assessment to focus on application and analysis rather than recall.

Periodic Table Contents

The periodic table section displays all 118 elements in standard format, showing atomic (proton) number, element symbol, element name, and relative atomic mass values. The layout includes entries such as hydrogen (H, 1.0), helium (He, 4.0), sodium (Na, 23.0), and chlorine (Cl, 35.5). Footnotes identify the lanthanides (elements 58–71) and actinides (elements 90–103) separately, reflecting their positioning in the full periodic table structure.

Unlike some revision resources, the AQA booklet presents relative atomic masses rounded to appropriate significant figures for examination calculations. Students should note that these values differ slightly from those used at GCSE level, where simpler whole-number approximations may have been acceptable. Those seeking additional context on how the periodic table is organised may find detailed periodic table explanations helpful for building foundational understanding.

Infrared Spectroscopy Data

Table A provides infrared absorption data with wavenumber ranges measured in cm⁻¹. This information enables students to identify functional groups within molecules by matching observed absorption peaks to documented bond stretching frequencies.

The overlap between certain absorption ranges—such as O-H stretches in both carboxylic acids and alcohols—requires students to interpret additional contextual information from question wording and other spectral data.

Nuclear Magnetic Resonance Spectroscopy

The booklet provides two dedicated NMR tables. Table B covers ¹H NMR chemical shift data expressed in delta parts per million (δ/ppm), while Table C presents ¹³C NMR chemical shift ranges for different carbon environments.

The ¹H NMR table includes proton types ranging from hydroxyl groups (ROH, 0.5–5.0 δ) through aromatic systems (Ar-H, 6.0–8.5 δ) to aldehydic protons (-CHO, 9.0–10.0 δ). The ¹³C NMR table similarly covers carbon environments from alkyne carbons (~80 δ) through carbonyl and carboxylic acid carbons (190–220 δ).

How Does the AQA A-Level Data Booklet Compare to GCSE and OCR Versions?

The AQA A-Level data booklet differs substantially from both its AS-Level counterpart and the resources provided by other examination boards. These differences have practical implications for students transferring between specifications or comparing revision materials.

A-Level Versus AS-Level (7405 vs 7404)

The A-Level specification includes the full data booklet with NMR tables and organic molecular structures. The AS-Level version, designated 7404, provides a simplified booklet covering the periodic table and infrared data only. This means A-Level candidates sitting Paper 2 receive additional spectroscopic reference material not available to AS candidates.

The Oxford AQA International version mirrors the standard A-Level content, including periodic table data and spectroscopy tables. Students following international specifications should verify their booklet matches these expectations.

A-Level Versus GCSE Resources

GCSE chemistry examinations do not provide a comparable data booklet insert. At GCSE level, the periodic table supplied is more basic, typically showing fewer data columns without the detailed atomic mass information required for stoichiometric calculations. Students progressing to A-Level should expect a significantly more comprehensive reference document.

Legacy AQA specifications such as 2420 offered data sheets, though these are now outdated and do not reflect current examination requirements. Current specification materials align with the 7405 framework introduced under the reformed A-Level structure.

AQA Versus OCR Comparison

OCR A-Level Chemistry provides its own data resources, which differ in presentation and content scope. While OCR includes similar periodic table and spectroscopy data, the exact layout and table formatting may vary. Students using past papers from alternative boards should familiarise themselves with both formats to avoid confusion during examinations.

How to Access the AQA A-Level Chemistry Data Booklet

While the data booklet is provided automatically during examinations, students benefit from reviewing specimen and past paper versions during revision. These materials are available through various educational repositories and tutoring platforms.

Physics and Maths Tutor hosts PDF copies of the AQA data sheet alongside past examination papers, allowing students to familiarise themselves with the exact format used in live assessments. The AQA Chemistry Data Sheet available through their platform provides a reliable reference matching official examination materials.

Save My Exams similarly offers a comprehensive overview of the data booklet contents, describing each table and explaining the information available within the insert. Their A-Level Chemistry Data Sheet resource provides context alongside the raw data.

The official AQA specification document outlines the assessment structure and confirms the data booklet provision. Students can access the specification at a glance to verify which papers include the data booklet insert.

What Information Remains Established Versus Uncertain?

The AQA A-Level specification establishes certain aspects of the data booklet provision definitively, while other details may vary depending on examination series and update cycles.

AQA updates examination materials periodically, though fundamental data values such as chemical shift ranges and infrared absorption frequencies remain consistent with established chemical principles. Students should always cross-reference their revision materials against the most recent specimen booklets available through official channels.

Why the Data Booklet Matters for Examination Success

The AQA A-Level Chemistry Data Booklet removes the burden of memorising extensive reference data, allowing assessment to focus on higher-order skills. Questions requiring identification of organic compounds through spectral analysis depend on candidates correctly interpreting data from the booklet rather than recalling values from memory.

Common examination errors include misreading chemical shift ranges, confusing similar absorption values (such as O-H stretches in acids versus alcohols), and failing to check the correct table for the required information. Familiarity with the booklet layout during revision helps candidates navigate to the correct data quickly during timed assessments.

Students who have reviewed past paper data booklets alongside their revision notes develop confidence in locating specific information efficiently. This preparation proves particularly valuable for Paper 2 questions that combine organic synthesis with analytical techniques requiring spectroscopic data interpretation.
