Question

why oxygen has higher ionization enthalpy than fluorine and neon !

please answer it quickly.

Answer 1

Answer:

That's why neon has a greater ionization energy than fluorine. ... They both have same number of shells, but neon has 1 proton and 1 electron more than fluorine, meaning that its attraction of the nucleus for the valence electrons should be greater.

Answer 2

Answer:

So as you move from carbon to nitrogen to oxygen to fluorine to neon, you're loading up more and more protons and electrons, but you're not increasing the number of energy levels in which the electrons can live. ... That's why neon has a greater ionization energy than fluorine.
