Antimony (pronounced /ˈæntɨmɵnɪ/ AN-ti-mo-nee) is a chemical element with the symbol Sb (Latin: stibium, meaning "mark") and atomic number 51. A metalloid, antimony has four allotropic forms. The stable form of antimony is a blue-white metalloid. Yellow and black antimony are unstable non-metals. Antimony is used in electronics and flame-proofing, in paints, rubber, ceramics, enamels, drugs to treat Leishmania infection and a wide variety of allo...

Antimony (pronounced /ˈæntɨmɵnɪ/ AN-ti-mo-nee) is a chemical element with the symbol Sb (Latin: stibium, meaning "mark") and atomic number 51. A metalloid, antimony has four allotropic forms. The stable form of antimony is a blue-white metalloid. Yellow and black antimony are unstable non-metals. Antimony is used in electronics and flame-proofing, in paints, rubber, ceramics, enamels, drugs to treat Leishmania infection and a wide variety of alloys.
Antimony in its elemental form is a silvery white, brittle, fusible, crystalline solid that exhibits poor electrical and heat conductivity properties and vaporizes at low temperatures. A metalloid, antimony resembles a metal in its appearance and in many of its physical properties, but does not chemically react as a metal. It is reactive with oxidizing acids and halogens. Antimony and some of its alloys are unusual in that they expand on cooling. Antimony is geochemically categorized as a chalcophile, occurring with sulfur and the heavy...
