Tungsten Element (Periodic Table)

Tungsten

Tungsten or Wolfram (W) is a chemical element of the periodic table, located in the group 6 and the period 6, and is having the atomic number 74. It is a hard, lustrous, greyish-white transition metal, whose name comes from the Swedish word “tung sten”, which means heavy stone. It has the highest melting point and boiling point of all metals.
