Zinc
Definition:
(n.) An abundant element of the magnesium-cadmium group, extracted principally from the minerals zinc blende, smithsonite, calamine, and franklinite, as an easily fusible bluish white metal, which is malleable, especially when heated.

Symbol Zn. Atomic weight 64.9.
(v. t.) To coat with zinc; to galvanize.
