Ionisation potential of O is less than that of N - explain

1st ionisation potential of Al is less than that of Mg- explain

Why is the 1st ionisation potential of B less than that of Be ?

The first ionisation energy of the Be is greater than that of B but the second ionisation energy of Be is less than that of B. explain.

Electron gain enthalpy of N is less than that of O. explain.

First ionisation enthalpy off Na is less than that of Mg, but second ionisation enthalpy of Na is higher than that of Mg. explain.

The first ionisation potential of carbon is more than that of boron while this trend is reverse in the case of second ionisation potential-explain.

Choose the number of correct statement(s) form the following: ist ionization potential of B is higher than that of Be electron affinity of O is higher than that of S [Ar] 4s^23d^3 is the electronic configuration of Mn^(+2) Iind ionisation potential of Na>ist ionisation potential of Na 1st ionisation potential of N>IInd ionisation potential of N electronegativity of Cl>electronegativity of F C rarr C^+2 change is called IInd ionisation potential of carbon energy is required to convert He rarr He^- conversion of o rarr o^2 exothermic

The first ionisation enthalpy of Mg is higher than that of Na but the second ionisation enthalpy is lower than that of Na -Explain.

The first ionisation enthalpy of C is higher than that of B but its second ionisation enthalpyislower. Explain ?
