Physical Properties Inorganic arsenic is a naturally occurring element in the earth's crust. Members of a group typically have similar properties and electron configurations in their outer shell. Elements are organised into blocks by the orbital type in which the outer electrons are found. It is highly poisonous, although it is used in some medicines to treat infections. Arsenic is a member of group Va of the periodic … Poisoning was some times diagnosed on the basis of a victim's garlic breath. On the pigment front they were hardly dare mentioned it, such a well worn tale, Napoleon's wallpaper just before his death is reported to have incorporated a so called Scheele's green which exuded an arsenic vapour when it got damp. It is mainly found in minerals. Some scientists think that arsenic may be an essential element in our diet in very, very low doses. Arsenic was known to the ancient Egyptian, and is mentioned in one papyrus as a ways of gilding metals. Uncombined elements have an oxidation state of 0. In small doses it is toxic and a suspected carcinogen. Most metalloids occur in several forms or allotropes where one might seem metallic while another one seems non-metallic. Arsenic is a bright silver-gray metalloid; its outermost electrons are not free to move in the crystal structure because they are fixed in position in a covalent bond. Cell Data: Space It has a garlicky odor, and is chemically stable, yet fairly brittle. Arsenic acid is a white hygroscopic solid.

Arsenic trioxide dust is readily absorbed from the lungs, but inhaled quantities are usually insufficient to cause acute systemic toxicity. Tin-white, Arsenic in the stable metallic form consists of light-greyish lustrous crystals possessing the symmetry of the ditrigonal scalenohedral class (dihexagonal alternating) of the rhombohedral system. Grey arsenic is the usual stable form with a melting point of 817 degree Celsius. The percentage of a commodity which is recycled. The name is thought to come from 'arsenikon', the Greek name for the yellow pigment orpiment. 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. Electron affinityThe energy released when an electron is added to the neutral atom and a negative ion is formed. Some elements exist in several different structural forms, called allotropes. Reticulated, reniform, stalagtitic, columnar, Melting Point: 818°C (at 36 atmospheres) It is a brittle, somewhat soft metalloid that is a little shiny. The yield varies slightly with the amount of alkali present, but the maximum at this temperature (350° C.) can occur in the absence of alkali. Arsenic trioxide has no odor and thus provides no warning of hazardous airborne concentrations. Physical properties The more common form of arsenic is a shiny, gray, brittle, metallic-looking solid. Once inside the body it bonds to atoms in the hair, so analysing hair samples can show whether someone has been exposed to arsenic. 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.. The less common form is a yellow crystalline solid . It is defined as being the charge that an atom would have if all bonds were ionic. Arsenic appears in three allotropic forms: yellow, black and grey; the stable form is a silver-gray, brittle crystalline solid. Arsenic is neither a metal nor a non-metal but instead joins a select but rather ill defined group of elements called the metalloids. Each allotrope has different physical properties.
