Gallium does not belong to a group. Although another name for it is gallia. It is used to detect solar neutrinos also used to make mirrors when painted on glass. Can change electricity into coherent light. It has no use in nature. It will react with air, water, acids, bases, and halogens. Gallium is typically found in its compound form in coal. Or other forms of smelting items. This particular metal is found almost anywhere in the world. But only found in materials we use. The element is not harmful to any living object. Gallium is fairly reactive. Gallium may be safe by itself but has been used in several different forms of nuclear bombs. Gallium has been used to stabilize plutonium but nothing has been used to stabilize it. Gallium has a very low melting point that it will just melt in your hands.
