AS Full Form

What is the full form of AS?

The Full form of AS is Autonomous System. or the full name of given abbreviation is Autonomous System. as is the symbol of the chemical element arsenic, with an atomic number of 33. Arsenic occurs in minerals with a combination of sulphur and metals. It sometimes also occurs as a pure elemental crystal. It is a metalloid and has various allotropes. Arsenic is mostly used in lead alloys (for example, in car batteries and ammunition). A typical n-type dopant in semiconductor electronic devices is arsenic. There are three types of arsenic allotropes. Arsenic in grey is most prevalent. It is a slightly glossy, brittle, and squishy metalloid. The density is 5.73 g/cm3. A semiconductor, that is. Rare and erratic are the characteristic properties of yellow arsenic. It is the most lethal allotrope. It is a nonmetal that is soft and waxy and resembles white phosphorus.

What Is AS?

Arsenic is an element in Group 15. Arsenic, a naturally occurring mineral and element, is widely distributed in the environment. Environmental sources of exposure to arsenic include:

• Air

• Soil

• Water

• Food.

Arsenic does not degrade because it is an element, hence, it stays in the environment.

Three major groupings can be used to categorise arsenic compounds:

• Inorganic

• Organic

• Arsine Gas

Physical And Chemical Characteristics of AS

• Arsenic is a semi-metal.

• When in metallic form, it is bright, silver-grey and breakable.

• The atomic number of As is 33

• Melting point- 1089 K or 816 °C (36 atm)

• Boiling point- 888 K or 615 °C (sublimation)

• Density- 5.7 g.cm-3 at 14°C

Uses of AS

Since ancient times, businesses have produced and utilised arsenic and its derivatives. Pharmaceuticals, wood preservatives, agricultural products, and applications in the mining, metallurgical, glass-making, and semiconductor sectors are just a few of the many present and historical uses of arsenic.

Until the 1970s, arsenic was used in several medical procedures. Leukaemia, psoriasis, and chronic bronchial asthma were treated with inorganic arsenic, and spirochetal and protozoal diseases were treated with organic arsenic found in medicines (ATSDR, 2007). Arsenic is also a well-known poison, and its compounds are therefore sometimes used as rat poisons or insecticides.

In semiconductors (gallium arsenide), arsenic is used as a doping agent for solid-state devices. Additionally, it's used for pyrotechnics, bronzing, and hardening shots. It can also be used to make special glass and preserve wood.
