Zinc belongs to the family of elements found in Group 12. Some other elements in this family are cadmium and mercury. These three elements are metals, but mercury is a metal that is liquid at room temperature, while zinc and cadmium are solids at room temperature.
This family of elements exhibits certain physical properties moving down the column. At the top of this column is zinc, cadmium and mercury. Moving down the column, the melting and boiling points decrease. However, the densities of these elements increase down the column.
Zinc has an atomic number of 30 and an atomic weight of 65.38 grams per mole. The production of zinc involves the electrolysis of zinc sulfate.
