Zinc is one of the oldest metals known to mankind.[1] It is a chemical element with the symbol Zn and atomic number 30. In some historical and sculptural contexts, it is (or was) known as spelter. It is a transition metal.
Zinc is most commonly used to galvanize other metals or alloys to make them corrosion resistant. It is also a main constituent of many coins.
Additionally, Zinc is a trace element essential to life. Deficiency can result in a number of problems, including impaired senses (at least taste, smell, and vision), slowed healing, and reduced immunity to infection. Extreme and prolonged deficiency can lead to kidney, liver, pancreas, or sickle cell diseases, or a host of other issues. Those with a deficiency will usually notice improvement in one or more of these areas if the increase their intake of this mineral.[2] (For example, viral infections can be more easily eradicated, food will taste better, vision will improve, and so on.)
Small pieces of zinc can burn with a blue flame.
