Cadmium. Cadmium (Cd) is a chemical element which is lustrous, silver white in nature. The metal is ductile and malleable. The common oxidation state of the element is 2. The element is used mainly for pigments, coatings and plating, and as stabilizers for plastics. Naturally is it most abundant compound occurs about 25,000 tons a year.

Cocoa powder and chocolate products, like other foods, are known to sometimes contain the toxic elements cadmium (Cd) and lead (Pb). The presence of Cd and Pb, which come from both natural and anthropogenic sources, may result from uptake from contaminated soil by the cacao tree (Mounicou et al. 2003 Mounicou S, Szpunar J, Andrey D, Blake C, Lobinski R .

Cadmium (elemental symbol Cd and CAS registry number 7440-43-9) is a member, along with zinc and mercury, of Group 12 (CAS IIB) of the Periodic Table of the Elements. It is generally characterized as a soft, ductile, silver-white or bluish-white metal, and is listed as 64 th in relative abundance amongst the naturally occurring elements.

Cadmium is a soft, bluish white metal that can be easily cut with a knife. Its chemical symbol is Cd and atomic number is 48. It has similar characteristics as zinc and mercury.
Definition of Cadmium. Cadmium is a chemical element.Elements are the building blocks for everything that has mass and takes up space. Its chemical symbol is Cd, not to be confused with the
Cadmium (Cd) is a naturally occurring metallic element that is used for electroplating and galvanization processes, in the production of pigments, in batteries, as a chemical reagent, and in miscellaneous industrial processes (ATSDR, 1989).

Cd, a chemical element of Group II of the periodic system of Mendeleev. Atomic number, 48; atomic weight, 112.40. Cadmium is a white, shiny, heavy, soft, ductile metal.
It has to do with the definition of transition metals. IUPAC (International Unit of Pure Applied Chemistry) defines transition metals as an element whose atom has a partially filled d sub-shell or which can give rise to cations with an incomplete d sub-shell. By this definition, cadmium is indeed a transition metal.
