(a) What are the similarities and differences between the 1s and 2s orbital of the hydrogen atom?
(b) In what sense does a 2p orbital have directional character? Compare the "directional" characteristics of the px and dx2-y2 orbital. (That is, in what direction or region of space is the electron density concentrated?)
(c) What can you say about the average distance from the nucleus of an electron in a 2s orbital as compared with a 3s orbital?
(d) For the hydrogen atom, list the following orbital in order of increasing energy (that is, most stable ones first): 4f, 6s, 3d, 1s, 2p.
