Elemental Tile

Tungsten from Wolframite

Tungsten is a hard, rare metal and when uncombined, tungsten is found naturally on Earth only in chemical compounds and this element is remarkable for its robustness and the fact that it has the highest melting point of all the elements and has a remarkable high density of 19.3 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead.

1783 by Fausto and Juan Jose de Elhuyar, Spain.

DISCOVERY

Swedish 'tung sten' meaning 'heavy stone' (symbol W is 'wolfram', from mineral wolframite).
