(a) With reference to Figure 6.18, what is the relationship between the number of nodes in an s orbital and the value of the principal quantum number?
(b) Identify the number of nodes; that is, identify places where the electron density is zero, in the 2px orbital; in the 3s orbital.
(c)What information is obtained from the radial probability functions in Figure 6.18?
(d) For the hydrogen atom, list the following orbital in order of increasing energy: 3s, 2s, 2p, 5s, 4d.
