Atomic number: 48
Year discovered: 1817
Discovered by: Friedrich Strohmeyer (1776-1835), a German chemist.
- Cadmium was discovered by Friedrich Stromeyer in 1817 from an impurity in zinc carbonate.
- He analyzed a bottle in an apothecary’s shop that contained zinc caronate.
- He noted that these particular samples turned yellow when heated, while pure zinc carbonate does not.
- He was persistent enough to follow this observation through and he eventually isolated some cadmium metal.
- Storage batteries using cadmium as one element have much longer lives than those using lead elements; and they have other advantages with respect to weight and the ability to be stored in a discharged condition.
