Following are answers to questions and solutions to problems at the end of Chapters 2-11. Problems are distinguished from questions by the letter P before its number.
True or False?
2.1. False. The atomic d states are fivefold-degenerate, so for the free atom any linear combination of the d functions in Table 2.1 and Fig. 2.3 is also a d function; they become space-oriented only under external perturbations that violate the spherical symmetry of the atom.
False. Hybridization of atomic functions takes place during (and is caused by) appropriate chemical bonding.
True. The orbital moment of s electrons is zero, so there is no spin-orbital interaction.
False. Separation between orbital and spin functions is possible approximately for light atoms where the spin-orbital interaction is weak and can be considered as a perturbation (Russell-Saunders coupling), but is not possible for heavy-atom compounds where the spin-orbital interaction cannot be considered as a small correction (jj coupling).
True. Since the atomic functions are normalized, the maximum of the overlap integral is achieved only when they fully coincide, and then the integral equals unity.

The electronic theory of transition metal systems pioneers a way of thinking in chemistry. This chapter is intended to introduce the reader to the objectives and main purpose of the book, to define the subject and the methods of its exploration, and to determine its "ecological niche" in the rapid
