Explain the first ionization energy of ne is 2081 kj/mol

Reference no: EM13503391

The first ionization energy of Ne is 2081 kJ/mol. The sodium ion Na+ is isoelectronic with Ne, but the ionization energy for Na+ is 4560 kJ/mol. Why is it harder to remove an electron from Na+ than from Ne if they are isoelectronic?
