74 - Tungsten transition metal
Discovered by Carl Wilhelm Scheele in 1783
- Atomic Radius (Å)
Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is volfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten.
