Uranium and thorium | Geoscience Australia

Uranium and thorium are both silvery white-grey radioactive metals that corrode to black oxide in air. They are both malleable (can be pressed into shape) and ductile (can be beaten and drawn into a wire) and are very reactive and so cannot be found in the environment in their elemental forms.
