Question

Explain why o has lower ionization enthalpy than n and f

Answer 1

Answer: o has lower ionization enthalpy then n because n has a half filled stable orbital which is more stable than oxygen configuration

And o has lower ionization enthalpy then f because f has high nuclear charge than oxygen which decrease the size of f atom which results in higher ionization enthalpy of fluorine

Explanation:

Answer 2

Answer:

Explanation:nitrogen has higher i.e. as it has less number of electrons as compaired to O and F . by this nucleus holds the electrons tightly . ... and hence O and F have lower i.e
