WebOverview Electron configuration. The electrons that determine valence – how an atom reacts chemically – are those with the highest energy.. For a main-group element, the valence electrons are defined as those electrons residing in the electronic shell of highest principal quantum number n. Thus, the number of valence electrons that it may have … WebWhile inner electrons (those not in the valence shell) typically don't participate in chemical bonding and reactions, valence electrons can be gained, lost, or shared to form chemical bonds. For this reason, …
