Cadmium Cadmium flakes
Cadmium is a bluish silvery, soft, ductile metal, which is a by-product in the production of zinc and other metals. It has a bad reputation, because it is in virtually every form very toxic and harmful to the environment. An important application are nickel-cadmium batteries, which, when defect, have to be disposed properly. Another one was cadmium sulfide, known as the pigment cadmium yellow.

Oxidized cadmium Oxidized and pure cadmium
Two oxidized pieces of cadmium, each about 2 cm in size. Cadmium monoxide, CdO, is a yellow-brown, highly toxic compound.
