Technetium's atomic number is 43 and its symbol is Tc. It is a silvery-gray transition metal, tarnishes slowly in moist air, and is the lightest radioactive element. It dissolves in nitric acid, aqua regia (nitro-hydrochloric acid) and concentrated sulfuric acid, but is not soluble in any strength of hydrochloric acid.

Its name comes from the Greek technetos, artificial. This is due to the element not appearing in nature. Therefore, it can only be produced in a laboratory. Technetium is a remarkable corrosion inhibitor for steel, and is an excellent superconductor.
