History

NameCadmiumZinc
HistoryThe element Cadmium was discovered by S. L Hermann,F. Stromeyer, and J.C.H. Roloff in year 1817 in Germany. Cadmium derived its name from the New Latin cadmia, from King Kadmos.The element Zinc was discovered by Indian metallurgists in year Before 1000 BCE in Germany. Zinc derived its name from the German word Zink.
