![]() In the form of a simple substance, metal atoms are interconnected by the so-called metallic bond.Ī metallic bond is a special type of bond that is unique to metals. In compounds with non-metals, typical metals form an ionic chemical bond. In compounds, metals always exhibit a positive oxidation state, usually +1 to +4. The best reducing agents are metals of groups I and II of the main subgroups. metal atoms donate electrons easily and are good reducing agents. They are the most chemically active, i.e. In periods, the alkali metals have the largest atomic radii. Metal atoms usually have large atomic radii. A feature of the structure of metal atoms is a small number of electrons in the external energy level, not exceeding three. However, many metals are amphoteric and can sometimes behave like non-metals. In addition, metals are the heaviest elements of groups IV, V, VI and VII. They are in groups I, II, III, in secondary subgroups of all groups. ![]() Mendeleev, out of 110 elements, 87 are metals. ![]()
