Atom

"The Atom"

Definition of the Antimony Element
A metallic element having four allotropic forms, the most common of which is a hard, extremely brittle, lustrous, silver-white, crystalline material. It is used in a wide variety of alloys, especially with Lead in battery plates, and in the manufacture of flame-proofing compounds, paint, semiconductor devices, and ceramic products. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. The Atomic Number of this element is 51 and the Element Symbol is Sb.

Periodic Table Group and Classification of the of the Antimony Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Antimony is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as one of the Metalloids has the properties of both metals and Non-Metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.

Facts about the Discovery and History of the Antimony Element
Dates back to Antiquity and used by many ancient peoples. First reported scientifically by Tholden in 1450. The first description of a procedure for isolating elemental antimony was in 1540 by Vannoccio Biringuccio.
