Arsenic is sometimes alloyed with lead to form a harder, more durable metal. It is present in the environment both naturally and due to certain human activities. Yellow arsenic has a specific gravity of 1.97 while grey arsenic has a specific gravity of 5.73. Low levels of arsenic are found in soil, water and air. In very small amounts, many of these metals are necessary to support life. Grey arsenic is the usual stable form with a melting point of 817 degree Celsius. 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 type of carcinogen that’s gray, silver, or white in color. 1. The arsenic leaches out into soil and rubs off the wood on to people or animals. Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health. Metalloids occur in the periodic table on either side of the staircase line that starts between boron and aluminum. When heated in air, arsenic combines with oxygen to form arsenic … Most arsenic gets into the body through ingestion of food or water. 1.1 Arsenic is a natural element which behaves like a metal. However, in larger amounts, they become toxic. Arsenic is also in the soil from smelters and some pesticides. No, arsenic is a metalloid, which means it has characteristics of both metals and non-metals. 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. What is arsenic? Until 2002, arsenic compounds were used to treat wood to prevent rot. Arsenic is found in water supplies worldwide with exposure of marine life. Arsenic is the most common cause of acute heavy metal poisoning in adults. Until recently, arsenic was commonly used in glassmaking. Arsenic is a non metal element. Arsenic in drinking water is a problem in many countries around the world, including Bangladesh, Chile, China, Vietnam, Taiwan, India, and the United States. Some areas of use include car batteries and bullets. Chemical properties Arsenic is a metalloid. A metalloid is an element that has properties of both metals and non-metals. Although it is sometimes found in its pure form as a steel grey metal, arsenic is usually part of chemical compounds. Arsenic may also be found in foods, including rice and some fish, where it is present due to uptake from soil and water. 1. Less commonly, metals including iron, copper, zinc, aluminum, beryllium, cobalt, manganese and arsenic may be considered heavy metals. What is the isotope of arsenic with a mass number of 75? 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. It has many different forms. Arsenic compounds are still used to make special glass, semi-conductors (gallium arsenide), some paints, dyes, metals, soaps, and drugs.
