Tungsten

Tungsten (W) is a steel-gray coloured metal that has the atomic number 74 in the periodic table. It is a Transition metal in Group 6. It has the symbol W.

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.

FAQ's

What is the Melting Point for Tungsten?

Tungsten has a Melting Point of 3410°F, meaning at 3410°F it will turn to a liquid.

What is the Boiling Point for Tungsten?

Tungsten has a Boiling Point of 5660°F, meaning at 5660°F it will turn to a Gas.

What is the Electronegativity of Tungsten?

Tungsten's Electronegativty is 2.36. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

What is the Heat of Vaporization of Tungsten?

Tungsten has a Heat of Vaporization of 824 kJ/mol.

Uses

Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives.

Sources

Occurs in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
