WebThe electrons in an atom can be divided into two groups: • Core electrons are the tightly bound electrons that are unaffected by chemical reactions. Core electrons reside in filled sublevels and form a spherical shell of negative charge around the nucleus that affects the amount of nuclear charge that the outermost electrons experience. • Web12 dec. 2024 · However, valence electrons feel an effective charge from the nucleus, or a charge brought about after the positive charge of the nucleus is subtracted by the number of core electrons. This effective charge is also felt by any valence electrons from other atoms, which is the main reason why stable bonds can occur.
