Stromeyer made his discovery after a request from the government to inspect the pharmacies in the town of Hildesheim, Germany. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. It is a soft, bluish-white metal which is easily cut with a knife. Some chemists don’t regard cadmium as a true transition metal, because it has a full shell of d electrons. Cadmium sulfide is used as a yellow pigment, and cadmium selenide is used as a red pigment, often called cadmium red. It could be part of the main body, but then the periodic table would be rather long and cumbersome. Almost all cadmium is obtained as a by-product in the treatment of zinc, copper, and lead ores.
