- Arsenic has been known since ancient times, though probably in compound form rather than in its pure state. It is used in combination with other materials in pigments, poison gases and insecticides (such as Paris Green, calcium arsenate and lead arsenate) and is well known from former use as a rat poison.

Arsenic trioxide Despite the well known toxicity of arsenic, arsenic trioxide has long been of biomedical interest, dating to traditional Chinese medicine, where it is known as pi-shuang (Chinese: 砒霜, Pinyin: pīshuāng) and is still used to treat cancer and other conditions, and to homeopathy, where it is called arsenicum album.

- Formerly the most important use of arsenic compounds, was as an insecticide sprayed in fields and orchards. This use has entirely disappeared in most countries, due to the poisonous nature of arsenic compounds.Arsenic contamination is a problem in some well-water and may be associated with mine drainage.ype: element. Description: Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.

Arsenic The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.rsenic 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.

Arsenic 1 It is also used in medical solutions such as Fowler’s solution for psoriasis. 2  Arsenic-74 an isotope is being used as a way to locate tumours within the body. 3  It produces clearer pictures than that of iodine. 4  Arsenic is added in small quantities to alpha-brass to make it resistant to leaching zinc. It has been used as a wood preserver because of its toxicity to insects, bacteria and fungi. 2  Arsenic is added to animal food to prevent disease and to promote growth. 3  Arsenic is used in the medical treatment of cancers such as acute promyelocytic leukemia.

Arsenic For the poison commonly called arsenic, see Arsenic trioxide. 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 is important to industry.

Arsenic Arsenic is a naturally occurring element widely distributed in the earth's crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.

- Arsenic trioxide is also important as a raw material for products containing arsenic. Because arsenic is an element like carbon and oxygen it does not break down in the environment into simpler substances-though it can change form and combine with other elements into molecules that have different chemical properties.Some forms of arsenic are quite toxic; others are less so.Most arsenic compounds are undetectable to the senses, since they have no smell or taste. But when arsenic is heated-by bright sunlight or in a laboratory experiment-it passes directly from its solid state to a gas and gives off a distinctive garlic odor.ost arsenic compounds are undetectable to the senses, since they have no smell or taste.

Arsenic 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. broad variety of sulfur compounds of arsenic are known. Orpiment (As2S3) and realgar (As4S4) are somewhat abundant and were formerly used as painting pigments. In As 4 S 10, arsenic has a formal oxidation state of +2 in As 4 S 4 which features As-As bonds so that the total covalency of As is still 3.

- The form of arsenic found naturally in foods (organic arsenic) does not seem to cause any harm. Other forms of arsenic (inorganic arsenic) are LIKELY UNSAFE for children when taken by mouth. Long-term exposure to arsenic in drinking water at a level of 50 mcg/L has been linked to reduced scores on intelligence tests in children.

- Arsenic pentoxide, potassium arsenite, and the sodium salts are soluble in ethanol. Arsenic, arsenic pentoxide, arse-nic trioxide, the calcium arsenites, lead arsenate, and potassium ar-senate are soluble in various acids. When heated to decomposition, arsenic compounds emit toxic arsenic fumes (HSDB 2009).

Arsenic Element Facts Melting point: 817 o C, 1090 K. Note: At normal atmospheric pressure arsenic does not melt when heated, it sublimes. i.e. when heated, arsenic undergoes a phase change directly from solid to gas. The melting point quoted above is for gray arsenic under a pressure of 28 atmospheres.

- In its metallic form it is bright, silver-grey and brittle. Uses. Arsenic is a well-known poison. Arsenic compounds are sometimes used as rat poisons and insecticides but their use is strictly controlled.rsenic 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 Properties of Arsenic. Arsenic has atomic number 33, so it has 33 electrons in the configuration 1s 2 2s 2 2p 6 3s 2 3p 2 3d 10 4s 2 4p 3. The same outer shell s 2 p 3 is shared by N, P, Sb and Bi, the two lighter elements above it in the periodic table, and the two heavier elements below.rsenic by itself likes to form the tetrahedral molecule As 4, in which each As is bound to the other three covalently (by sharing electrons). Phosphorus does exactly the same thing. As 4 is a yellowish gas that condenses to a yellow, waxy solid with density about 2.0 g/cc. The gas has a characteristic garlic-like odor.

Arsenic The primary use of metallic arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon.
