Question

The ionization enthalpy of o is less than n​

Answer 1

Explanation:

Since there are two electrons in the first orbital of the O sublevel, there is greater electronic repulsion in the 2p sublevel for O than N. Therefore, it is easier to remove an electron from the O than the N, and the ionization energy of O is lower than N

Answer 2

Explanation:

ionization enthanpy means that the amount of energy provided to an atom so that it can loose one electron it decrease as we go down in periodic table it is anti proportional to size of atom
