Nickel (element)

Nickel is the chemical element with atomic number 28 and symbol Ni. In the 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. It is one of the few magnetic elements (iron and cobalt are the others).

Nickel is often found in coins, wires, meteorites, and steel alloys.

Nickel (US coin)

A nickel is a coin worth five cents. It is currently made of cupronickel. During World War II, nickel was needed for the war effort, and the composition was made up of copper, silver, and manganese. The nickel currently features Thomas Jefferson on the obverse side, and Monticello on the reverse.
