Chapter 12, Problem 12.114(choose chapter or problem)
Consider the following ionization energies for aluminum. Al(g) 88n Al1(g) 1 e2 I1 5 580 kJ/mol Al1(g) 88n Al21(g) 1 e2 I2 5 1815 kJ/mol Al21(g) 88n Al31(g) 1 e2 I3 5 2740 kJ/mol Al31(g) 88n Al41(g) 1 e2 I4 5 11,600 kJ/mol a. Account for the increasing trend in the values of the ionization energies. b. Explain the large increase between I3 and I4. c. Which one of the four ions has the greatest electron affinity? Explain. d. List the four aluminum ions given in the preceding reactions in order of increasing size, and explain your ordering. (Hint: Remember that most of the size of an atom or ion is due to its electrons.)
