Arsenic is a chemical element with the symbol As and atomic number 33 Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystalArsenic is a metalloidIt has various allotropes, but only the gray form, which has a metallic appearance, is important to industry The primary use of arsenic is in alloys of lead (for example, in car Nickel is a chemical element with the symbol Ni and atomic number 28 It is a silverywhite lustrous metal with a slight golden tinge Nickel belongs to the transition metals and is hard and ductilePure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer Nickel WikipediaNickel Nickel is a nonessential metal of great environmental concern because it is widely used in the production of coins, jewelry, stainless steel, batteries, medical devices, carbon particles as well as in Ni refinery, plating and welding 28 Although, epidemiological, animal, and cell culture studies have found nickel compounds to be carcinogenic, the mechanism(s) of nickel carcinogenesis Epigenetics in metal carcinogenesis: Nickel, Arsenic
