The INTERNET Database of Periodic Tables


There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.

2005 Geologist's Periodic Table

Atmophile Elements - noble gases and covalently bonded gaseous molecules. The atoms and molecules are attracted by weak van der Waals forces and so these elements remain gaseous at room temperature.

Lithophile Elements - Those elements which form ionic bonds generally have filled outer electron shells. They typically bond to oxygen in silicates and oxides.

Siderophile Elements - The metals near iron in the periodic table that exhibit metallic bonding, have a weak affinity for oxygen and sulfur and are readily soluble in molten iron. Examples include iron, nickel, cobalt, platinum, gold, tin, and tantalum. These elements are depleted in the earth crust because they have partitioned into the earth's iron core.

Chalcophile Elements - The elements that bond to S, Se, Te, Sb, and As. These bonds are predominantly covalent in character.

As discussed in more detail here.
