The Royal Society of Chemistry website has four periodic tables, with links to detailed information on each element.
- The main table has standard information about the various elements, plus their supply risk.
- A history table shows when each element was discovered and who by, and the origin of its name.
- An alchemy table shows 16 elements known to alchemists (antimony, arsenic, bismuth, copper, gold, iron, lead, magnesium, mercury, phosphorus, platinum, potassium, silver, sulfur, tin and zinc).
- A trends table displays the density, atomic radius, electronegativity, melting point, boiling point and first ionisation energy of elements.
The site also has some resources for the International Year of the Periodic Table.
