Question

Arrange b c n o in increasing order of their ionization enthalpy

Answer 1

1-It is the amount of energy/enthalpy that is needed to remove an electron from an atom in its gaseous state.

2-Ideally, the ionization enthalpy increases with a decrease in atomic size, thus the expected trend is B < C < N <O.

Answer 2

Answer:

the ionization enthalpy increases with a decrease in atomic size, thus the expected trend is B < C < N <O.
