The existence and properties of gallium were predicted by a Russian The M 3 + state for gallium, indium, and thallium is energetically less.
Groups 3 -11 are termed transition elements. Transition elements image showing Group numbers: group 3 periodic periodicity for group 3 chemical elements.
Because of their chemical inertness, the elements in this group are called the Nobel Gases: charged positive ion, which has the stable electronic configuration of its neighbouring Nobel Gas element in the periodic table. However, hydrogen has none of the metallic properties of the alkali metals. Group III Elements. Group 1 Alkali Metals - GCSE Chemistry
