Unformatted text preview: r momentum quantum number, l (subshell) e.g., for phosphorus: 1s2 2s2 2p6 3s2 3p3 (spread in the shells) 15 electrons. Additional terminology: Valence Shell: Those orbitals in an atom of the highest occupied (‘outermost’) principal level (n) and the orbitals of partially filled sublevels of the lower principal quantum number (n-1) (exterior) Valence electrons are those that occupy the valence shell orbitals. All other electrons not in the valence shell are core _______________ electrons.
