Tantalum
Tantalum (Ta; atomic weight 180.95, atomic number 73; named by a 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 almost completely immune to chemical attack.
