Tungsten is named from the Swedish name for the mineral, tungstate which it is found in ‘scheelite’ which means heavy stone. It is a rare metal found in minerals such as wolframite. It was isolated in 1783 by Jose and Fausto Elhuyar who found that they could isolate the metal from the mineral wolframite. The element s very robust and has one of the highest melting points of any element discovered and has a density similar to that of gold and uranium. However due to its crystal structure is brittle. It is used in light bulb filaments and x-ray tubes. It also has a purpose in radioactive shielding. It is a solid metal at room temperature with a melting point of 3422°c and a boiling point of 5930°c.
