Answer the following questions about first ionization energies.
(a) Generally ionization energies increase on proceeding across a period, but this is not true for magnesium (738 kJ/mol) and aluminum (578 kJ/mol). Explain this observation.
(b) Explain why the ionization energy of phosphorus (1012 kJ/mol) is greater than that of sulfur (1000 kJ/mol) when the general trend in ionization energies in a period would predict the opposite.
