TantalumTantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant. It is part of the refractory metals group, which are widely used as minor components in alloys.
