Protactinium is a silver metallic element that belongs to the actinide group. It is malleable, shiny, silver-grey, and radioactive. It does not tarnish rapidly in air, it is attacked by oxygen, steam and acids, but not by alkalis. It is superconductive at temperatures below 1.4°K.

Due to its scarcity, high radioactivity and toxicity, there are currently no uses for protactinium outside of basic scientific research.
