Nickel (Ni)

Nickel ([Ar]3d⁸4s²) (CAS 7440-02-0) is a lustrous, silvery-white metal with excellent resistance to corrosion. It is hard, malleable, ductile, ferromagnetic, and a reasonable conductor of heat and electricity. A member of the iron-cobalt group of metals, nickel is extensively used for making stainless steel and other corrosion resistant alloys. In nature, nickel is a component in most meteorites, even serving as one of the criteria for distinguishing a meteorite from other minerals.
