The Periodic Table

For ease of printing (should you feel so inclined), I've moved the "introductory" and explanatory text to the bottom of the page, just below the Key to Element Borders & Colours.

I prepared this particular Periodic Table of the Elements back 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 a few anomalies between even those). It was published online in February 2005, but in August 2008 I completely revised and updated it with more accurate data. At the same time, I provided an alternative Wide Format arrangement which includes all the same information but brings inline the Lanthanoid and Actinoid Series that usually appear below the main table.

For each element you'll find the following information:

The Standard Atomic Weights given in the table above were determined by the International Union of Pure and Applied Chemistry (IUPAC) Commission on Isotopic Abundance and Atomic Weights, and are as updated in their 2007 revisions. The values are presented in a concise notation whereby the standard uncertainty is given in parentheses next to the least significant digit to which it applies; for example, the value for Iron is 55.845(2), which is the concise form of 55.845 ± 0.002. Values enclosed in square brackets, e.g. [223] (Francium), indicate the Mass Number of the longest-lived isotope of the element.

On the previous incarnation of this page I recommended not attempting to print it. However, thanks to the wonders of CSS, you should now find either format relatively easy to print should you feel so inclined (remember that the Dynamic Site Menu conveniently disappears when printing). Note however that you'll probably need to scale it down to fit it onto a single A4 page. Landscape orientation is recommended.
