is arsenic a metal

However, in larger amounts, they become toxic. Arsenic is released into the environment by the smelting process of copper, zinc, and lead, as well as by the manufacturing of chemicals and glasses. List of Heavy Metals If you go by the definition of a heavy metal as a metallic element with a density greater than 5, then the list of heavy metals is: Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. Arsenic is the most common cause of acute heavy metal poisoning in adults. What is arsenic? Arsenic in drinking water is a problem in many countries around the world, including Bangladesh, Chile, China, Vietnam, Taiwan, India, and the United States. When heated in air, arsenic combines with oxygen to form arsenic … Although it is sometimes found in its pure form as a steel grey metal, arsenic is usually part of chemical compounds. Arsenic is a type of carcinogen that’s gray, silver, or white in color. 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. Arsenic is a non metal element. Yellow arsenic has a specific gravity of 1.97 while grey arsenic has a specific gravity of 5.73. Arsenic is an element found in nature, and in man-made products, including some pesticides. It has many different forms. Until 2002, arsenic compounds were used to treat wood to prevent rot. Metalloids occur in the periodic table on either side of the staircase line that starts between boron and aluminum. Arsenic is a naturally occurring allotropic pnictogen and metalloid trace element with atomic symbol As, atomic number 33, and atomic weight 74.92 that is found in water, air, food, and soil, and has a role as a micronutrient. In very small amounts, many of these metals are necessary to support life. Arsenic is sometimes alloyed with lead to form a harder, more durable metal. Grey arsenic is the usual stable form with a melting point of 817 degree Celsius. No, arsenic is a metalloid, which means it has characteristics of both metals and non-metals. Less commonly, metals including iron, copper, zinc, aluminum, beryllium, cobalt, manganese and arsenic may be considered heavy metals. Most arsenic gets into the body through ingestion of food or water. Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. 1. A metalloid is an element that has properties of both metals and non-metals. Low levels of arsenic are found in soil, water and air. Arsenic may also be found in foods, including rice and some fish, where it is present due to uptake from soil and water. The arsenic leaches out into soil and rubs off the wood on to people or animals. 1.1 Arsenic is a natural element which behaves like a metal. 1. Arsenic is also in the soil from smelters and some pesticides. Arsenic is found in water supplies worldwide with exposure of marine life. Arsenic compounds are still used to make special glass, semi-conductors (gallium arsenide), some paints, dyes, metals, soaps, and drugs. Chemical properties Arsenic is a metalloid. Some areas of use include car batteries and bullets. Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health.
