    J=2 when L and S are parallel pointing in the same direction: the angular momenta then add up.

    J=1 when they are perpendicular: they both are 1 and both point in a totally different direction, so do not add up nor cancel.

    J=1 when parallel and in opposite directions: they cancel that way.
