Question

Select the false statement below.

A. Fluorine has a greater first ionization energy than iodine, and the reason for this is because fluorine has a greater amount of shielding of outer electrons by inner electrons than does iodine.
B. The following process is an endothermic process and represents the first ionization energy of an atom A:
A(g) ? A1+(g) + e1-

C. Phosphorus has a greater first ionization energy than magnesium, and the reason for this is because P has a greater effective nuclear charge (Zeff) than Mg.
D. The first ionization energy of an atom is smaller than the second ionization energy of the same atom.

Explanation / Answer

The first ionization energy of an atom is smaller than the second ionization energy of the same atom.
