Tantalum
Tantalum (Ta, Ar,standard 180.95, atomic number 73; named by the Swedish chemist Anders Gustaf Ekeberg, who discovered tantalum, in honour of Tantalus, a Phrygian king in Greek mythology) is a chemically very resistant metal. At low temperatures (< 150°C) tantalum is chemically almost inert.Web
