Does NA or Ne have a higher second ionization energy?
The ionization enthalpy of Na+ ion (second ionization enthalpy of sodium ) is more than twice that of Ne. The Na+ ion has higher effective nuclear charge (+9) than Ne (+8). So, the electrons in the outer shell (2s2 2p6) are more tightly bound to the nucleus in Na+ ion than in the neutral Ne atom.
Why the 2nd ionization enthalpy of Na is higher than Ne?
This is because Ne has a stable octet and whereas Sodium has tendency to lose the outermost electron. Neon is a noble gas and it is really difficult to remove even one electron from its stable configuration. Hence here is a comparasion of 2nd ionization enthalpy of sodium and 1st ionization enthalpy of Neon.
Which one has greater ionization energy Na+ or Ne?
Na+ has higher value of ionization enthalpy than Ne, though both have same electronic configuration. The number of protons and thus nuclear charge in Na+ is more than Ne. So, the nuclear attraction on the valence electrons is more in Na+ than Ne. Thus, Na+ has higher value of ionization enthalpy than Ne.
Which element has the highest 2nd ionization energy?
Thus lithium element will have the largest second ionization energy.
What is the second ionization energy of Na?
This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms….1st–10th ionisation energies.

Why Na has higher ionization enthalpy than Ne though both have same electronic configuration?
Na^(+) has higher value of ionization energy than Ne, though both have same electronic configuration – Explain. Na+ has more number of protons (11) than Ne (10). So the nucleus of Na+ holds the electrons strongly. Hence the ionisation energy of Na+ is greater than Ne.
Which has higher ionization energy B or be?
Comparing the first ionization energies of Be and B, beryllium has a higher ionization energy because its radius is smaller. boron has a higher ionization energy because its radius is smaller.
Which element has the largest second ionization energy mg Na F?
Out of all the elements given sodium (Na) will have the largest second ionization energy. Now, if second electron is removed it will be from completely filled 2p orbitals which are highly stable.
