Periodic table (GCSE)
What is here?
The periodic table below is based on the ones used by the different examination boards.
The group numbers 1 to 0 (the top ones) are used in most GCSE courses. The group numbers 1 to 18 were recommended by IUPAC in 1988. These are only used in OCR courses at the moment.
There is a summary at the bottom of the page. It shows the differences between this table and the ones used by three examination boards.
The lanthanoids and actinoids are not shown in GCSE periodic tables (only in A Level tables).
Select an element using your mouse (or finger on touch devices). You will see its melting and boiling points, electronic configuration (first 20 elements only), and if it is radioactive or toxic.
