periodic table atoms database csv sql and xml

Chemist friends, you often need to use data from the Period of Elements table, also called the Mendeleev table. But it is constraining to search on Google each time a value is necessary (density, radius of covalency, melting point…). This small article proposes to download the 118 atoms of this table with the data with their associated data. If you are a chemist you will surely find daily use in all of this data.

This database is provided free of charge by the site.
