History

History
The element Nickel was discovered by Axel Fredrik Cronstedt in year 1751 in Sweden. Nickel derived its name from from Swedish kopparnickel, containing the German word Nickel, 'goblin'
The element Hafnium was discovered by Dirk Coster in year 1923 in Denmark. Hafnium derived its name derived its name from from Hafnia, the New Latin name for Copenhagen
