History

History
The element Hafnium was discovered by Dirk Coster in year 1923 in Denmark. Hafnium derived its name from from Hafnia, the New Latin name for Copenhagen
The element Tungsten was discovered by Carl Wilhelm Scheele in year 1783 in Spain. Tungsten derived its name derived its name from from the Swedish tung sten, 'heavy stone' (W is wolfram, the old name of the tungsten mineral wolframite)
