IGCSE Periodic Table
as the exam papers print it.
The IGCSE chemistry exams print a Periodic Table in the paper. Below are Cambridge’s, for 0620 and 0971, and Pearson Edexcel’s, for 4CH1, with each element’s atomic number, symbol and relative atomic mass as the board gives them, and where the two differ.

- Printed in every 0620 and 0971 paper, with the line: the volume of one mole of any gas is 24 dm³ at room temperature and pressure (r.t.p.).
- Groups are numbered I to VIII; the block between Groups II and III has no group number.
- All 118 elements, with the lanthanoids (57 to 71) and actinoids (89 to 103) in two rows below.
- A dash means no relative atomic mass is given. Only chlorine (35.5) has a decimal; copper is 64.

- The lanthanoids (58 to 71) and actinoids (90 to 103) are left out; lanthanum and actinium are marked *.
- The relative atomic masses of copper (63.5) and chlorine (35.5) are not rounded to whole numbers.
- Masses in square brackets are given for radioactive elements. The table stops at 111; elements 112 to 116 are noted as reported but not fully authenticated.

Cambridge and Edexcel, side by side.
- Copper. Cambridge gives 64; Pearson Edexcel gives 63.5. Chlorine is 35.5 on both. Of the 83 elements both tables show, 16 have a different value, all but copper because Cambridge prints a dash where Pearson gives a mass in brackets: Tc, Po, At, Rn, Fr, Ra, Ac, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg.
- The order in each box. Cambridge puts the atomic number above the symbol and the relative atomic mass below; Pearson Edexcel the other way round.
- Group numbers. Cambridge numbers groups I to VIII; Pearson Edexcel 1 to 7, with the noble gases as Group 0.
- What is shown. Cambridge shows all 118 elements, with the lanthanoids and actinoids below the table and the molar volume of a gas underneath. Pearson Edexcel leaves out elements 58 to 71 and 90 to 103 and stops at 111.
- OxfordAQA. The OxfordAQA International GCSE Chemistry (9202) specification prints the same values as Pearson Edexcel, in the same order, and adds elements 112 to 118 with masses in brackets.
Where the table costs marks.
- Copy symbols exactly. Examiners marked down symbols written with the wrong capital or small letter, although the Periodic Table was in the paper: Co is cobalt, CO is carbon monoxide. Cambridge 0620 examiner report, June 2024
- Read the period from the shells. Some candidates did not know that the number of occupied electron shells gives the period, and swapped the labels for protons and neutrons. Pearson 4CH1 examiner report, June 2025
- Use the masses the paper gives. Relative formula masses come from the relative atomic masses in the table, so a calculation uses copper as 64 on a Cambridge paper and 63.5 on an Edexcel one.

IGCSE Periodic Table:
questions students ask.
Is the Periodic Table given in the IGCSE chemistry exam?
Yes. Cambridge prints it in every 0620 and 0971 paper, and Pearson Edexcel prints it in the 4CH1 question paper. Students do not need to learn the relative atomic masses, but they do need to read the table quickly and copy symbols exactly.
Is copper 63.5 or 64 in IGCSE chemistry?
It depends on the board. Cambridge’s table gives copper as 64; Pearson Edexcel’s and OxfordAQA’s give 63.5. Chlorine is 35.5 on all three. Use the value printed in the paper you are sitting.
Why is the last group VIII on one table and 0 on another?
They are the same group, the noble gases. Cambridge numbers its groups I to VIII; Pearson Edexcel and OxfordAQA number them 1 to 7, with the noble gases as Group 0.
What is the molar volume of a gas in IGCSE chemistry?
Cambridge prints it under the Periodic Table in every paper: one mole of any gas has a volume of 24 dm³ at room temperature and pressure.
Which elements does the IGCSE Periodic Table leave out?
Pearson Edexcel and OxfordAQA leave out the lanthanoids and actinoids (58 to 71 and 90 to 103), keeping lanthanum and actinium. Pearson’s table also stops at element 111. Cambridge shows all 118 elements.
Can I print this Periodic Table?
Yes. Print this page prints the tables without the rest of the site. It is our layout of the values each board prints, for practice; in the exam, use the table in the question paper.
