Solution
Ionization energy: Ionization energy is defined as the amount of energy required to remove an electron from the valence shell of an gaseous atom.
Reason for Fluorine(F) having larger Ionization energy than Oxygen(O):
- Fluorine is a more electronegative element than oxygen.
- Due to the high electronegativity of fluorine, the outermost electrons of fluorine are more tightly held by the nucleus than oxygen.
- So, removing the outermost electron of fluorine requires more energy than removing the outermost electron of oxygen.
- As a result, the ionization energy of Fluorine is higher than that of oxygen.
