The group 12 elements have multiple effects on biological organisms as cadmium and mercury are toxic while zinc is required by most plants and animals in trace amounts. Zinc is an essential trace element , necessary for plants, [ 111 ] animals, [ 112 ] and microorganisms . [ 113 ]
Zinc has an electron configuration of [Ar]3d 10 4s 2 and is a member of the group 12 of the periodic table. It is a moderately reactive metal and strong reducing agent . [ 48 ] The surface of the pure metal tarnishes quickly, eventually forming a protective passivating layer of the basic zinc carbonate , Zn
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...

In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
Most zinc is in the brain, muscle, bones, kidney, and liver, with the highest concentrations in the prostate and parts of the eye. [11] Semen is particularly rich in zinc, a key factor in prostate gland function and reproductive organ growth. [12] Zinc homeostasis of the body is mainly controlled by the intestine.
