Introduction:
This page should be familiar to anyone who did Chemistry in High School, as it is a great visual aid to the differing properties of the basic physical elements.
For even more information, such as grouping by metals vs non-metals, we recommend a visit to the Visual Elements Periodic Table which is an arts and science collaborative project from the Royal Society of Chemistry (RSC).
The behaviour of elements in the same group, or in the same period, tends to be similar, so hover over the group numbers (top row) or period numbers (left-most column) to highlight.
Unlike many printed copies, both the Lanthanoids and the Actinoids are shown in the correct place, but can be condensed if necessary.
