(n.) A bright silver-white metallic element. It is of the iron group, and is hard, malleable, and ductile. It occurs combined with sulphur in millerite, with arsenic in the mineral niccolite, and with arsenic and sulphur in nickel glance. Symbol Ni. Atomic weight 58.6.
(n.) A small coin made of or containing nickel; esp., a five-cent piece.
