Workers exposed to arsenic in metal-smelting operations, and the community around the factories from which arsenic is emitted, have an increased risk for lung cancer. Arsenic is a Block P, Group 15, Period 4 element. Black arsenic is a poor conductor of electricity and is brittle with a glassy appearance. Overview Information Arsenic is a trace element. The physical properties of arsenic depend largely on how it is processed. Although some forms of elemental arsenic are metal-like, the element is best classified as a nonmetal. Arsenic is a chemical element with the symbol As and atomic number 33. Black arsenic can be prepared by cooling arsenic vapor at 100 o C - 200 o C. It is glassy, brittle and a poor electrical conductor. It burns in air to make garlic -smelling arsenic trioxide. Arsenic, as well as some of its compounds, do not have a liquid state; they sublime.

Pharmacokinetic Properties of Arsenic Species after Intravenous and Intragastrical Administration of Arsenic Trioxide Solution in Cynomolgus Macaques Using HPLC-ICP-MS . The elements share certain general similarities in chemical behaviour, though they are clearly differentiated from one another chemically, and these similarities reflect common features of the electronic structures of their atoms.…, …in the outer shell, while arsenic lacks three. Yellow is meta-stable, is a poor electrical conductor, and has no metallic sheen. 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. The fracture of this mineral is uneven. The ground state electronic configuration of neutral arsenic is [Ar].3d 10.4s 2.4p 3 and the term symbol of arsenic is 4 S 3/2.. Arsenic: description Your user agent does not support the HTML5 Audio element. Arsenic is a natural element that is widely distributed in the earth's crust, hydrosphere and biosphere.In the environment, it combines with oxygen, chlorine, and sulfur to create a series of inorganic arsenic compounds. 2. Source: Los Alamos National Laboratory (2001), Crescent Chemical Company (2001), Lange's Handbook of Chemistry (1952), CRC Handbook of Chemistry & Physics (18th Ed.) Grey arsenic is the most common. 4. Arsenic is a chemical element in the nitrogen group and the twentieth most abundant element on the Earth’s surface. Atmosphere/p.p.m. Physical and chemical properties – Physical and chemical properties of arsenic are listed below – Atomic number of the element arsenic is 33. Electron configuration and elemental properties of arsenic. The less common form is a yellow crystalline solid. 5. In addition to the many uses of arsenic compounds as herbicides and pesticides, they have in several instances been employed as pharmacological agents. Arsine (AsH 3), a colourless poisonous gas composed of arsenic and … by Qiaoli Shi 1, Mingyan Ju 2, Xiaoxia Zhu 1, Hui Gan 1, Ruolan Gu 1, Zhuona Wu 1, Zhiyun Meng 1,* and Guifang Dou 1,* 1. It is steel-gray in color, crystalline, tarnishes readily in air, and is rapidly oxidized to arsenous oxide (As2O3) upon heating (arsenous oxide exudes the odor of garlic). Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.Inorganic arsenic … It is found in several foods including seafood, poultry, grains (especially rice), bread, cereal products, mushrooms, and dairy products. Properties of Arsenic Image will be uploaded soon. This mineral has a metallic luster with black streak. Halogens attack arsenic, as does sulfur, and the element will combine directly with many metals forming arsenides. With moisture, arsenic reacts slowly forming arsenic(V) oxide. Atomic Number – Protons, Electrons and Neutrons in Arsenic. International Atomic Energy Agency ENSDF database (Oct 2010). 3. Arsenic and its compounds are poisonous. Arsenic may similarly be replaced by metals, but the replacement cannot always be predicted from the position of arsenic in the electrochemical series, this power of replacement being a highly specific property which depends on the nature of the metal and the conditions of the experiment.
