The net result of the angular portions is this picture above. There are
two lobes of both phases. In each of the xy, yz, and xy orbitals, the
axes lie in the plane of the screen, such that the two axis meet at the
center of four lobed figure. The axis form planes of symmetry that fall
in between the lobes.. In the case of the x
2 - y
2 ,
the x and y axis form two planes of symmetry that bisect the figure
along the lobes.
