History

History
The element Sodium was discovered by Humphry Davy in year 1807 in United Kingdom. Sodium derived its name from from the English word soda (natrium in Latin)
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
