Which period 2 element has successive first through seventh ionization energies (kJ/mol)of E_i1 = 1,402;E_i2 = 2,856;E_i3 = 4,578;E_i4 = 7,475;E_i5 = 9,445;E_i6 = 53,267;and E_i7 = 64,360? A)B B)C C)N D)O

Question

Quizplus · Accepted Answer

The large jump in ionization energy between the 5th and 6th ionizations indicates the removal of an electron from a new, lower energy level, which is characteristic of nitrogen (N) after removing its 5 valence electrons.
