Identify the element of Period 2 which has the following successive ionization energies, in kJ/mol. IE₁, 1314 IE₂, 3389 IE₃, 5298 IE₄, 7471
IE₅, 10992 IE₆, 13329 IE₇, 71345 IE₈, 84087

Question

Quizplus · Accepted Answer

The element with the given ionization energies has a first ionization energy of 1314 kJ/mol, which is consistent with the first ionization energy of oxygen (1314.3 kJ/mol). Additionally, the increasing ionization energies suggest the removal of electrons from an increasingly positive ion, which is consistent with the electronic structure of oxygen. None of the other choices have ionization energies that match the given values or follow the expected trend based on electron configuration.
