History
History |
The element Copper was discovered by Middle East in year 8000 BC in unknown place. Copper derived its name from from English word (Latin cuprum) |
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 |
