ARSENIC By, Jeremy Rubert

Why is it called Arsenic? This element's name was derived from "arsenikon," the Greek word for yellow orpiment pigment. It is also believed that Albert Magnus discovered the element in 1250 A.D. who created it by heating soap together with orpiment. Arsenic was mined by early Chinese and Egyptian civilizations, the elements toxic properties were definitely discovered early on.

Physical Properties of Arsenic Melting Point: 1090 [or 817 °C (1503 °F)] (under pressure) K Boiling Point: 887 [or 614 °C (1137 °F)] (sublimes) K Liquid Range: (no liquid phase at normal pressure) Color: Metallic Gray Texture: Rough

Arsenic is a Metalloid Arsenic has some properties of metals and non-metals. Arsenic is a grey, metallic looking solid. It is about one-third lighter than iron, brittle, and moderately hard. It is stable in dry air but develops a golden bronze patina in moist air, which blackens on further exposure.

Uses for Arsenic Arsenic is used in ammunition manufacturing because it helps to create harder and rounder bullets. Arsenic is used in small quantities in semi-conductor manufacturing. It is used as a preservative in tanning and taxidermy, as well as on the exterior of wood such as deck and playground materials. When present in high concentrations, arsenic can kill you instantly. When arsenic is present in very small amounts (soils or water supply), it can kill and poison you over many years.
