The Periodic Table

Please note that these are the two pages on my website for which I do not claim to meet Level AAA conformance to the Web Content Accessiblity Guidelines (WCAG) due to the many different combinations of text and background colours used in the table. However, as all colours are applied using Cascading Style Sheets (CSS), if you use assistive technology when browsing the Web I hope you will be able to make it work for you.


I first prepared this particular Periodic Table of the Chemical Elements in 1999 to help me with my GCSE studies, consulting various different sources, of none of which I could guarantee the accuracy (and there were anomalies between even those – largely due to revisions over the years to some elements' Standard Atomic Weights). I published it online in February 2005, but in August 2008 I completely revised and updated it with more accurate data. I've since updated it again in September 2022 with the most recently added new elements, however for ease of future maintenance I don't anticipate adding any more elements, and I've deleted all the Standard Atomic Weights (which continue to be reviewed every couple of years, and so would relatively quickly risk becoming out-of-date). These can most reliably be found either on Wikipedia (at the link above) or at their source, the International Union of Pure and Applied Chemistry (IUPAC).

Also in August 2008 I provided an alternative Wide Format arrangement of the Periodic Table which includes all the same information but brings inline the Lanthanoid Series and Actinoid Series that more commonly appear below the main table.

For each element in the table you'll find the following information:

Finally, there's a Key to Element Borders & Colours below.
