Crystal Structure
Simple Hexagonal
Tarix
Cadmium was discovered by German chemist Friedrich Stromeyer in 1817 as an impurity in zinc carbonate.
Stromeyer noted that some impure samples of calamine (zinc carbonate) changed color when heated but pure calamine did not.
Cadmium was independently discovered by German chemist Karl Hermann in 1818.
