Tungsten | Chemical elements

Tungsten was discovered in 1783 by Fausto and Juan Jose de Elhuyar. Its name derives from the Swedish words "tung sten" which means "heavy stone". However, its symbol’s origin derives from tungsten’s German name which is "wolfram". Tungsten’s melting point is at 3410.0 °C (3683.15 K, 6170.0 °F) and its boiling point is at 5660.0 °C (5933.15 K, 10220.0 °F).
