The successive ionization energies of an element show a large jump between the 3rd and 4th ionization energies. This element is most likely in Group:
A.1 (IA)
B.13 (IIIA)
C.2 (IIA)
D.3 (IIIA)
Explanation
Core Concept
A large jump between the 3rd and 4th ionization energies indicates that the element has 3 valence electrons. Removing the 4th electron requires breaking into a filled inner shell, so the element is in Group 13 (IIIA).
Correct Answer
D3 (IIIA)
