PGGC – 11 Chandigarh. Vector model of an atom. The total angular momentum of an atom result from the combination of the orbital and spin angular . momenta. of its electrons. Angular momentum is a vector quantity, so we can represent the total angular momentum by means of a vector J obtained by the addition of orbital angular momentum L and spin angular momentum S vectors. This leads to the vector atom model. .
