The shapes of orbital may be represented by boundary surface diagrams. These boundary surface diagram give the most probable regions. S-orbitals are non-directional while p-, d- and f-orbitals have different orientations given by m_l values. These boundary surfaces also have sperical nodes or radial nodes and nodal planes which depend upon the values of n and l. Does d_z^2 orbital has zero electron density in xy plane ?
