<onlyinclude>'''Zinc''' is the 30th [[element]] on the [[periodic table of elements|periodic table]]. It is a silvery-white [[metal]] that tarnishes in [[air]], and has many uses in society.</onlyinclude> Zinc is the 4th most common metal in use, next to [[iron]], [[aluminum]] and [[copper]].

Over 13 million [[tonne]]s of zinc are produced worldwide each year, primarily in China, Australia, and Peru.<ref>Tolcin, A. C. (2015). ''Mineral Commodity Summaries 2015: Zinc'' (PDF). United States Geological Survey. Retrieved May 27, 2015. Available: http://minerals.usgs.gov/minerals/pubs/commodity/zinc/mcs-2015-zinc.pdf</ref> Considering the [[embodied energy]] in zinc production is, on average, between 49-55 [[megajoule|MJ]]/[[kilogram|kg]], this puts the total annual [[energy]] required to produce zinc between 637-715 [[joule|petajoules]] (1015 joules).<ref name=unep>UNEP.

==Uses of Zinc==

Roughly a third of all zinc is used to galvanize other metals - this means it protects the metal from rusting. An object such as an iron nail is protected from corrosion by giving it a protective layer of zinc. Galvanized [[steel]] is used for [[motor vehicle|car]] bodies, street lamp posts, and suspension bridges.<ref name=rsc>Royal Society of Chemistry. (Accessed May 18, 2016). ''Zinc'' [Online], Available: http://www.rsc.org/periodic-table/element/30/zinc</ref>

Zinc is also used to make useful alloys such as brass, where it is mixed with up to 95% copper. Brass is a very common alloy, and was used more than 2500 years ago by the Ancient Romans. Today, brass is used to make musical instruments, screws and other hardware.<Ref name=jef/> Zinc is also alloyed with [[lead]] and [[tin]] to make solder, used in joining electrical pieces together such as pairs of copper wire.

Zinc has also long been used in [[battery|batteries]], due to its high [[power density]] and excellent electrochemical properties. Newer zinc batteries are also rechargeable, as well as being recyclable.<ref>International Zinc Association. (Accessed May 23, 2016). ''Batteries'' [Online], Available: http://www.zinc.org/batteries/</ref>

===In living things===

Zinc is essential for life, as it forms the site for over 20 metallo-enzymes. The average human contains around 2.5 [[gram]]s of zinc at any one time, and intakes around 15 milligrams per day from foods such as beef, lamb, or cheese.<Ref name=rsc/>

Too much zinc is dangerous however, as it can be [[carcinogen]]ic in excess.
