Nickel is a light grey color metal, which is quite strong and very resistive to corrosion. The name of the element is believed to take roots from the German expression meaning Devil’s copper. Despite the fact that nickel can be found in cells of all living organisms, this element is very carcinogenic even in small doses. It is impossible to find pure nickel on our planet, only in minerals, as well as on meteorites coming to our planet (one of them has landed in Canada and now provides about 15 per cent of the world’s nickel supply). Nickel used to be a key element for producing coins, and it is also used to produce batteries. Due its high resistance to corrosion, nickel is used to cover various metallic parts in order to prevent their corrosion. Numerous alloys of nickel have wide industrial uses.
