Definition of the Cadmium Element
A soft, bluish-white metallic element occurring primarily in zinc, copper, and lead ores, that is easily cut with a knife and is used in low-friction, fatigue-resistant alloys, solders, dental amalgams, nickel-cadmium storage batteries, nuclear reactor shields, and in rustproof electroplating.

Origin / Meaning of the name Cadmium
The name originates from the Greek word kadmeia  and from the Latin word cadmia

Classification of the Cadmium Element
Cadmium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. An Element classified as a Transition Metals is ductile, malleable, and able to conduct electricity and heat.

Facts about the Discovery and History of the Cadmium Element
Cadmium was discovered in Germany by Fredrich Stromeyer  in 1817

Occurrence the Cadmium Element
Obtained from zinc refining, mining, smelting
Greenockite is the only cadmium mineral of importance and is nearly always associated with sphalerite

Associated Uses of Cadmium
Batteries - Nickel Cadmium
Pigments
Coatings and platings
Barrier to control nuclear fission
Televisions
Nickel cadmium batteries

Cadmium and the Periodic Table
Check out Cadmium on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Cadmium for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Cadmium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Cadmium is just one element that can be found.
