Group 12 element facts for kids
A group 12 element is a group in the periodic table of chemical elements. It includes zinc, cadmium, mercury, and copernicium. Copernicium is not stable so its properties are not clear. They all have low melting and boiling points. Mercury is even a liquid. Zinc is the least electronegative and most reactive of the Group 12 elements.
