Properties Thorium is an actinide metal that is ductile, soft, and silvery in color. It has a face-centered structure and is very reactive. THORIUM (REVISED) Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. Overview Thorium is a member of the actinide family. The actinide elements are located in Row 7 of the periodic table [1]. They have atomic numbers between 90 and 103.

This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth.
