==Nickel (element)==
'''Nickel''' is the [[chemical]] element with [[atomic number]] 28 and symbol '''Ni'''. In the [[periodic table of the elements|periodic table]] it is one of the transition metals. It is a silvery white metal and is often used for its resistance to [[oxidation]] and conductivity of heat and electricity.<ref>http://www.webelements.com/webelements/elements/text/Ni/key.html</ref> It is one of the few magnetic elements ([[iron]] and [[cobalt]] are the others).

Nickel is often used as a catalyst similar to [[platinum]]. Though less effective, it is also far less expensive and thus is an attractive option.
Nickel is often found in coins, wires, [[meteorite|meteorites]], and [[steel]] alloys.
