On this page I'll provide comprehensive data for Thorium. I hope you profit from it.
Thorium Overview
Name Origin
Named for Thor, Norse god of thunder.
Symbol
Th (Thorium)Description
Heavy, gray, soft, malleable, ductile, radioactive metal.
Discovery
Discovered By: Jöns Berzelius
Year: 1828
Location: Sweden
Sources
Found in various minerals like monazite and thorite.
