What is the density of cadmium?

Cadmium is a shiny metal with a bluish cast (shade) to it. It is very soft and can almost be scratched with a fingernail. Its melting point is 321°C (610°F) and its boiling point is 765°C(1,410°F). The density of cadmium is 8.65 grams per cubic centimeter.

Similarly, what is Cadmium used for?

Cadmium's major use is in batteries (especially rechargeable nickel–cadmium, NiCad, batteries). As a result of its low coefficient of friction and its high fatigue resistance, cadmium is used in alloys for bearings. Cadmium is used in low melting alloys and is a component of many kinds of solder.
