For a main-group element, a valence electron can exist only within the outermost electron shell; for a transition metallic, a valence electron can also be in an inside shell. Student have been introduced the day past to the 5 different chemical reactions that present that conservation of mass can happen several of the way during a chemical response. The most reactive sort of metallic factor is an alkali metal of group 1 (e.g., sodium or potassium); this is because such an atom has solely a single valence electron.
The farther right in each transition metal sequence, the decrease the vitality of an electron in a d subshell and the much less such an electron has valence properties. Thus, although a nickel atom has, in principle, ten valence electrons , its oxidation state never exceeds four. For zinc, the 3d subshell is full in all known compounds, although it does contribute to the valence band in some compounds.
