The s orbital is spherical (nondirectional) because: A-the angular wave function of an s orbital is defined by the quantum number, ell. B-an s orbital has angular nodes. C-at a particular distance from the nucleus, the electron probability is the same in all directions. D-the angular wave function for all s orbitals is a constant. E-the angular wave function of an s orbital varies with the principal quantum number (n).

Angular and radial wave functions for s and p orbitals The equations for the angular and radial wave functions for the s and p orbital may be useful when completing this tutorial.
