Which of the following elements have the highest values of ionization energy?

مندرجہ ذیل میں سے کون سے عناصر میں آئنائزیشن توانائی کی اعلی اقدار ہیں؟

Transition elements

Inert gases

Alkaline earth metals

None of these

Inert gases (noble gases) have the highest ionization energy.

Due to their fully filled stable electron configuration.

Removing an electron requires a lot of energy since they have low reactivity and strong nuclear attraction.
