WebElements: The Periodic Table on The Web

As of Dec. 2006, there are 117 chemical elements, according to the excellent webelements periodic table web site:

The number of known elements does change.

The chemogenesis web book uses the WebElements periodic table as its master data source, and it does not attempt to duplicate it. These are the data fields associated with Web Elements Scholar Edition:

Abundance of elements (Earth's crust)
Abundance of elements (oceans)
Abundance of elements (sun)
Abundance of elements (Universe)
Abundance of elements (in human body)
Accurate mass of the isotopes
Atomic number
Atomic weight
Biological role
Block in periodic table
Boiling point
Bond enthalpy (diatomics)
Bond length in element
Colour (color)
Compounds
