Below are data on the first four ionization energies for a fictitious element X.

First ionization energy = 500 kJ/mol
Second ionization energy = 2000 kJ/mol
Third ionization energy = 3500 kJ/mol
Fourth ionization energy = 25000 kJ/mol

From the data, which of the following statements is incorrect?

A. X could belong to Group III A
B. The fourth ionization energy is much greater than the third ionization energy because X3+ consists of a noble-gas core or a pseudo-noble-gas core
C. The third ionization energy is greater than the second ionization energy because X2+ has a bigger charge than X-
D. X could belong to Group IIIB
E. X could belong to group VA.
