Ground state configuration: [Ar]4s23d10.

This is a "happy" element because all of its electron orbitals are filled!

"If you can't think, and your feet stink, you need Zinc."

This old saying tells of a couple of symptoms of low zinc levels. Zinc is important in helping the absorption and the metabolism of vitamins and carbohydrates. It is found especially in the reproductive organs and defieciency may slow growth or even cause infertility.

By eating a balanced diet your zinc intake should be adequate, as it is found in meat, wholegrains, nuts, seeds, green vegetables, milk, eggs and oysters.

Zinc has been found to alleviate acne in some cases.

Taking more zinc than your system requires, for example, 150mgs per day for 6 weeks or so, may cause weakening of the immune system, and over 200 mgs per day may cause collapse. If you are taking a dosage of zinc at more than 15 mg per day it is advised not to take within 1 hour of food.

Zinc (?), n. [G. zinc, probably akin to zinn tin: cf. F. zinc, from the German. Cf. Tin.] Chem.

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. It is not easily oxidized in moist air, and hence is used for sheeting, coating galvanized iron, etc. It is used in making brass, britannia, and other alloys, and is also largely consumed in electric batteries. Symbol Zn. Atomic weight 64.9

[Formerly written also zink.]

Butter of zinc Old Chem., zinc chloride, ZnCl2, a deliquescent white waxy or oily substance. -- Oxide of zinc. Chem. See Zinc oxide, below. -- Zinc amine Chem., a white amorphous substance, Zn(NH2)2, obtained by the action of ammonia on zinc ethyl; -- called also zinc amide. -- Zinc amyle Chem., a colorless, transparent liquid, composed of zinc and amyle, which, when exposed to the atmosphere, emits fumes, and absorbs oxygen with rapidity. -- Zinc blende [cf. G. zinkblende] Min., a native zinc sulphide. See Blende, n. (a) -- Zinc bloom [cf. G. zinkblumen flowers of zinc, oxide of zinc] Min., hydrous carbonate of zinc, usually occurring in white earthy incrustations; -- called also hydrozincite. -- Zinc ethyl Chem., a colorless, transparent, poisonous liquid, composed of zinc and ethyl, which takes fire spontaneously on exposure to the atmosphere. -- Zinc green, a green pigment consisting of zinc and cobalt oxides; -- called also Rinmann's green. -- Zinc methyl Chem., a colorless mobile liquid Zn(CH3)2, produced by the action of methyl iodide on a zinc sodium alloy. It has a disagreeable odor, and is spontaneously inflammable in the air. It has been of great importance in the synthesis of organic compounds, and is the type of a large series of similar compounds, as zinc ethyl, zinc amyle, etc. -- Zinc oxide Chem., the oxide of zinc, ZnO, forming a light fluffy sublimate when zinc is burned; -- called also flowers of zinc, philosopher's wool, nihil album, etc. The impure oxide produced by burning the metal, roasting its ores, or in melting brass, is called also pompholyx, and tutty. -- Zinc spinel Min., a mineral, related to spinel, consisting essentially of the oxides of zinc and aluminium; gahnite. -- Zinc vitriol Chem., zinc sulphate. See White vitriol, under Vitriol. -- Zinc white, a white powder consisting of zinc oxide, used as a pigment.
