How many electrons in a full valence shell
WebIn chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each contributing one valence electron.. The presence of valence electrons can determine the … WebIf the valence shell is full (contains 8 electrons), the atom is inert, that is, it does not form chemical bonds with other atoms. Octet rule - if an atom’s valence shell is not full, the …
