'''Antimony''' ('''Sb''') is a [[toxic]], flaky, brittle [[element]] with the symbol Sb (Latin: stibium, meaning "mark") and atomic number 51. It does not react with air, but burns brightly when ignited. Since it is not a metal, antimony is a poor [[conductor]] of both [[heat]] and [[electricity]]. The stable form of antimony is a blue-white [[metalloid]]. Yellow and black antimony are unstable non-metals. Antimony is used in flame-proofing, paints, batteries, ceramics, enamels, as a hardener for lead and other metals, and in a wide variety of alloys, electronics, and rubber. The ancient Egyptians used black stibnite as eye make-up.

Antimony is a member of the "pnictogen" (group 15) of the periodic table. This is the area that has a metal near the bottom ([[bismuth]]) and some nonmetals near the top ([[nitrogen]]). Antimony in between -- It is one of the few elements which is neither a [[metal]] or a non-metal.

Antimony was known as an element at least as far back as the alchemists. It was first scientifically studied in 1707 by Nicolas Lemery.
