Antimony (Sb) is a toxic, flaky, brittle element with the symbol Sb (Latin: stibium, meaning "mark") and atomic number 51. It is one of the few elements which is neither a metal or a non-metal. 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, ceramics, enamels, a wide variety of alloys, electronics, and rubber.
