Problem
Which statement about the first ionization energies of nitrogen and oxygen atoms is correct?
(1) IE1(N)<IE1(O) because oxygen has two paired electrons in its partly filled sublevel
(2) IE1(N)>IE1(O) because oxygen has two paired electrons in its partly filled sublevel
(3) IE1(N)<IE1(O) because oxygen loses an electron from a higher sublevel than nitrogen
(4) IE1(N)>IE1(O) because oxygen loses an electron from a higher sublevel than nitrogen
