Angular functions: 'shapes'
The mathematical functions for atomic orbitals may be described as a product of two factors: the radial wavefunction defines the behavior of the electron as a function of distance from the nucleus (see below); the angular wavefunction shows how it varies with the direction in space. Angular wavefunctions do not lay on n and are characteristic features of s, p, d,...orbitals.
