Antimony is an element of group 15. It has multiple allotropic forms. The stable form of antimony is a blue-white metalloid. Yellow and black antimony are unstable non-metals. It is used in flame-proofing, paints, ceramics, enamels, and rubber. Antimony is attacked by oxidizing acids and halogens. Antimony was firstly reported in 1540 by Vannoccio Biringuccio. Antimony has 37 isotopes, 2 of them are stable and naturally occurring.
Antimony is alloyed with other metals to increase their hardness. Also it is used in the manufacture of a few special types of semiconductor devices. This element is also used in plastics and chemicals. A few kinds of over-the-counter cold and flu remedies use antimony compounds.
