Tungsten is a hard, heavy, grey-white,
metallic element, with a symbol W, an atomic
number of 74, and a relative atomic mass
number of 183.85. It occurs in the minerals
wolframite, scheelite, and hubertite. It has
the highest melting point of any metal,
6,170°F (3,410°C) and is added to steel to
make it harder, stronger, and more elastic.
