what is the etymology of hafnium
Hafnium was discovered by Dirk Coster and George Charles von Hevesy at 1923 in Denmark. Origin of name: from the Latin name Hafnia meaning Copenhagen. Hafnium was thought to be present in various zirconium minerals many years prior to its discovery, in 1923, which was credited to Dirk Coster and George Charles von Hevesey. It was finally identified in zircon (a zirconium ore) from Norway, by means of X-ray spectroscopic analysis.
