Nickel


General Facts About Nickel

The element Nickel is in group 10, period 4, block d of the periodic table. Its atomic number is 28 and its relative atomic mass is 58.693. In total nickel has about 5 stable electrons. When placed at room temperature the element Nickel is a solid. It boiling point is 2913 oC and melting point is 1455 oC. In 1751 Cronstedt discovered nickel in kupfernickel (niccolite or nickel arsenide). The metal was prepared by heating nickel oxide with charcoal, a reaction typical of many metals. .

When placed at room temperature the element Nickel is a solid. It boiling point is 2913 oC and melting point is 1455 oC. When looking at it you will see a silvery metal that resists corrosion even at high temperatures.

The minerals which contain the most nickel are garnierite and pentlandite. Nickel is mainly used in the making of alloys such as stainless steel. Nickel has long been used in coins - the US five-cent piece (known as a ‘nickel’) is 25% nickel and 75% copper. The metal is obtained commercially from pentlandite (nickel sulfide) and pyrrhotite (magnetic pyrites) of the Sudbury region of Ontario, Canada. This district produces about half of the nickel in the world. Siberia, Russia also produces a large portion of the world’s nickel.

Discovery

In 1751 Cronstedt discovered nickel in kupfernickel (niccolite or nickel arsenide). The metal was prepared by heating nickel oxide with charcoal, a reaction typical of many metals. The name comes from the German word Nickel, meaning Satan or "Old Nick". The nickel-containing ore was called kupfernickel, meaning Old Nick's copper or false copper.
