Antimony is a minor ore of the element antimony, although most antimony comes from antimony compounds (namely Stibnite), which are much greater in abundance. Antimony has a very interesting property: It is similar to water, in that instead of contracting when it solidifies, like all other matter, it expands. For this reason, it is useful

It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as ‘regulus’, melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of antimony were known as early as 4000 BC.

The electronic structure of antimony closely resembles that of arsenic, having three half-filled orbitals in the outermost shell. Thus, it can form three covalent bonds and exhibit +3 and −3 oxidation states. The electronegativity of antimony is lower than that of arsenic. It can act as an oxidizing agent and reacts with many metals to form
