Element Arsenic.

white arsenic trioxide Number of Electrons, Protons, Neutrons, Symbol and Name Name: Arsenic Symbol: As Number of Protons: 33 Number of Electrons: 33 Number of Neutrons: 42 Melting horizontal surface: 817.0 °C (1090.15 °K, 1502.6 °F) Boiling office: 613.0 °C (886.15 °K, 1135.4 °F) History Arsenic: From the Latin discourse arsenicum, the Greek word arsenikon and the Arabic word Az-zernikh. Arsenic is pronounce AR-sn-ik. Although the early Chinese, Greek exploit arsenic compounds and Egyptian civilizations, it is believed that Albertus Magnus, a German alchemist, first determine arsenic itself. Properties Melting Point: 1090 K (1502.6°F) Boiling Point: 887 K (1137.2°F) Density: 5.776 grams per three-dimensional centimeter Phase at dwell Temperature: Solid Estimated Crustal abundance: 1.8 milligrams per kilogram Estimated Oceanic Abundance: 3.7-3 milligrams per liter Number of stable Isotopes: 1 Electron Shell word melodic line: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3 Elemental arsenic occurs in deuce inviolable modifications: yellow, and grey or metallic, with specific gravities of 1.97, and 5.73, respectively. The element is a steel Grey, very brittle, crystalline, semimetallic (metalloid) solid. It tarnishes in air, and when heated rapidly oxidizes to arsenous oxide which has a garlic odour. Arsenic and its compounds be poisonous. Upon heating system arsenic and some minerals containing arsenic, it sublimes (transfers from the solid to the bobbleeous state, without passing by means of with(predicate) the liquid state).

Chemical properties Synonyms for arsenic be arsenic-75, metallic arsenic, arsenic black, arsenicals, and colloidal arsenic. The inorganic arsenic compounds be solids at normal temperatures and are not likely to volatilize. In water, they range from quite meltable (sodium arsenite and arsenic irate) too practically insoluble (arsenic trisulfide). Some organic arsenic compounds are gases or low-boiling liquids at normal temperatures. Poisonous gas is produced by arsenic in a fire. Arsenic well-nigh acid or acid mist can clitoris a very plaguey gas, arsine. Twenty-one arsenic compounds...
