CADMIUM (ge), derived from kadmia, the meaning of "soil", was discovered in 1817. With zinc exists in nature. It is a kind of fine metal to absorb neutrons, the rods can slow down the nuclear chain reaction rate in the atomic reactor, and useful in the zinc - cadmium cell. Its distinctive made of cadmium sulphide yellow pigment, widely popular with artists.
Cadmium is silvery white, shiny metal, melting temperature 320.9 ℃, boiling point 765 ℃, the density of 8650 kg/m3; . With toughness and ductility. Cadmium in wet air oxidation and slow loss of metallic luster, heating surface brown oxide layer. High temperature response to cadmium and halogen halide cadmium. Can also be directly combined with sulfur, cadmium sulfide. Cadmium, soluble in acid, but not soluble in alkali. Cadmium oxidation state for + 1 + 2. Solubility of cadmium cadmium oxide and hydroxide are small, they are soluble in acid, but not soluble in alkali. Cadmium can form a variety of complex ion, such as Cd (NH3), Cd (CN), CdCl, etc.
