Valence electrons are the electrons in the outer energy level of an atom that can participate in http://www.youtube.com/watch?v=iuj_hw_MFN8 (9:41). 1.
In chemistry and physics, a valence electron is an outer shell electron that is 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, both atoms in the bond contribute one valence electron in order to form a shared pair. The presence of valence electrons can determine the element's chemical properties, such as its valence—whether it may bond with other elements and, if so, how readily
