which group on the periodic table contains magnesium Group 2 what is group 12 element? It is a group of chemical elements in the periodic table which includes  zinc (Zn), cadmium (Cd) and mercury (Hg) what are the physical properties of the element which is denoted as zn? It is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish what role do they play biologically? It is an essential trace element for humans and other animals, for plants and for microorganisms. what is its use in industries? Zinc oxide is widely used as a white pigment in paints and as a catalyst in the manufacture of rubber to disperse heat, the semiconductor properties of zinc oxide make it useful in varistors and photocopying products, etc. does it aid to increase the weight?? Yes, zinc supplementation alone had a statistically significant effect on linear growth and body weight gain what will happen to our body on its deficiency? Depressed growth, diarrhea, impotence and delayed sexual maturation, alopecia, eye and skin lesions, impaired appetite, altered cognition, impaired immune functions, defects in carbohydrate utilization, and reproductive teratogenesis can you list some of its applications? Corrosion-resistant zinc plating of iron is the major application for zinc, other applications are in electrical batteries, small non-structural castings, and alloys such as brass, etc.

Zinc [SEP] Introduction
To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow". The element was probably named by the alchemist Paracelsus after the German word "Zinke" (prong, tooth). German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746. Work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron (hot-dip galvanizing) is the major application for zinc.
