Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. It makes excellent cutting and drilling tools, including a new ‘painless’ dental drill which spins at ultra-high speeds. This is because they are not very energy efficient; they produce much more heat than light. Tungsten (atomic number 74, symbol W) is a metal and chemical element that was discovered in 1781 by the Swedish mineralogist and chemist Torbern Bergman.
