Textbook Question
Chapter 7, Problem 75SCQ
The energies of the orbitals in many elements have been determined. For the first two periods they have the following values:
- (a) Why do the orbital energies generally become more negative on proceeding across the second period?
- (b) How are these values related to the ionization energy and electron attachment enthalpy of the elements?
- (c) Use these energy values to explain the observation that the ionization energies of the first four second-period elements are in the order Li < Be > B < C.
