The above shows the successive ionization energies for the element aluminum, Al. Why is there such a large increase in ionization energy between the 3rd and 4th energies of this element?
The atomic radius of the element increases.
After the 3rd, the ion become isoelectronic with the element neon.
Ionization energy always shows a large increase from the 3rd to the 4th for all elements.
The ion formation results in a large particle from the atom and the energy increases.
