Thorium (atomic number 90, symbol Th) is a metal and chemical element with radioactive properties. It was discovered by Jons Berzelius and Morten Esmark in 1828. Properties Thorium is an actinide metal that is ductile, soft, and silvery in color. It has a face-centered structure and is very reactive.

However, one isotope, 232 Th, is relatively stable, with a half-life of 14.05 billion years. Thirty radio isotopes of Thorium have been characterized. The known isotopes of thorium range in mass number from 209 to 238.
