Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.
arsenic is in group 15 and period 4. Wood preservation The toxicity of arsenic to insects, bacteria and fungi makes it an ideal component for the preservation of wood.
Arsenic doesn't seem much like a metal in its so called yellow form, but it also has a grey form known tellingly as metallic arsenic. Yellow arsenic has a specific gravity of 1.97 while grey arsenic has a specific gravity of 5.73. Grey arsenic is the usual stable form with a melting point of 817 degree Celsius.
Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood.
In order to form liquid arsenic, the atmospheric pressure must be increased. At 28 times standard atmospheric pressure, arsenic melts at a temperature of 1090 K. If it were also measured at a pressure of 28 atmospheres, arsenic's boiling point would be higher than its melting point, as you would expect.

Arsenic was discovered by Albertus Magnus (DE) in 1250. The origin of the name comes from the Greek word arsenikon meaning yellow orpiment. It is a steel-grey, brittle semi-metal that resists water, acids and alkalis. It tarnishes in air, burns in oxygen and is highly toxic by inhalation or ingestion. Arsenic is found in mispickel (arsenopyrite).
Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. Arsenic is a type of carcinogen that’s gray, silver, or white in color. Arsenic is ...
