Question

Select the false statement below.

A(g) ? A1+(g) + e1-

A. Sodium has a greater first ionization energy than sulfur, and the reason for this is because Na has a greater effective nuclear charge (Zeff) than S. B. Fluorine has a greater first ionization energy than iodine, and the reason for this is because fluorine has a lesser amount of shielding of outer electrons by inner electrons than does iodine. C. The first ionization energy of an atom is smaller than the second ionization energy of the same atom. D. The following process is an endothermic process and represents the first ionization energy of an atom A:

A(g) ? A1+(g) + e1-
