Antimony IPFS

Antimony is a chemical element with symbol Sb (from Latin stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Antimony MMTA

Although antimony is known as a metal, it is a very poor conductor of electricity and is toxic to humans. Antimony is not attacked by dilute acids or alkalis, and is stable in air at room temperature, but it will react with oxygen if heated to form antimony trioxide, Sb2O3.

Sulfur Encyclopedia

Many ores are compounds of a metal and oxygen or a metal and sulfur. Compounds that contain two elements, one of which is sulfur, are called sulfides. For example, a beautiful gold-colored mineral is called pyrite, or fool's gold, because it looks so much like real gold. Pyrite is iron sulfide (FeS 2). Sulfur was known to ancient peoples.
