Vedclass · Answer

(C) Ionization energy is the energy required to remove an electron from a gaseous atom or ion. When the fourth electron is removed,the atom achieves a stable electronic configuration (such as a noble gas configuration). Removing the fifth electron would require breaking this stable configuration,which demands a significantly higher amount of energy. Therefore,a large jump between the $4^{th}$ and $5^{th}$ ionization energies indicates that the atom has $4$ valence electrons.

$A$ large difference between the fourth and fifth ionization energies indicates the presence of
