Antimony is a shiny, grey metalloid represented by the symbol Sb. It has properties of both metals and non-metals and is brittle in nature.

Antimony is mainly used in alloys to increase hardness and strength. It is added to lead to make batteries, bullets, and cable coverings stronger. Antimony compounds are also used in flame retardants, medicines, and glass manufacturing. Though useful, antimony must be handled carefully because excessive exposure can be harmful.
