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 Palladium was discovered by William Hyde Wollaston in year 1803 in United Kingdom. Palladium derived its name derived its name from from the then recently discovered asteroid Pallas, considered a planet at the time
