Standard disclaimer - this is just my experience as an individual. I joined before the wars, and I can't tell you why, and I've stayed for a variety of reasons. But one of the reasons I've stayed in is all the people I served with who stayed in, fighting in those pointless wars.. I'm not a killer, so I couldn't contribute that way.
Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. Arsenic is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry.
Description: Arsenic's name comes from the Greek term for an arsenic compound, orpiment (arsenic trisulfide). Arsenic is a metalloid element, which, like phosphorus, has two main forms. One is a brittle, gray metallic form and the other is a yellow, non-metallic solid.Yellow arsenic is the more reactive and unstable of the pair. Arsenic is stable, being unaffected by air, water, most acids and alkalis.Arsenic has no liquid phase; the solid sublimes directly into a vapor.rsenic has semiconductor properties and is used in making transistors. It is also used in alloys, glass production, pyrotechnics and wood preservatives. An arsenic-gallium compound is used in making lasers.
