Ionization energy of Mg is greater than that of Al. Why?

Answer»

Solution :`Mg(Z-12)1s^(2)2s^(2)2p^(6)3S^(2)`
`AL(Z=13)1s^(2)2s^(2)2p^(6)3s^(2)3p^(1)`
Although the NUCLEAR charge of aluminium is greater than that of magnesium, I.E of Mg is greater than that of Al. It is because Mg ATOM has more STABLE configuration than Al atom.
`therefore I.E_(1)` of MggtI.E_(1)` of Al.
