Question

Supposing the energy of fourth shell of hydrogen atom is -50 a.u. (arbitrary unit). What would be its ionization potential ?​

Answer 1

Answer:

Due to stable half filled p-orbital the nitrogen molecule does not want to lose electrons easily. Therefore its first ionization potential is greater than that of oxygen but less than fluorine. Because Nitrogen has a higher affinity for its electrons than Oxygen does for the first ionization level.
