AI overview

Thorium is a naturally radioactive metal with a silvery appearance that turns olive-grey when exposed to air, and it's relatively soft with a high melting point. It's notable for being highly reactive—particularly when finely divided—and for having chemistry dominated by a specific oxidation state that makes it chemically active.
