1) Ionisation energy increases from left to right along a period. As all the given four elements belong to the same period..Their I.E's increase.
2) E.C of Mg - 3s*2
E.C of Al - 3s*2 3p*1
As Mg has fully filled orbital electronic configuration..It requires more energy to remove electron.
s > p > d > f

EmmaW1:
What does "filled orbital" have anything to do with energy? I don't understand.
filled orbital has more stability..hence it requires more energy to remove an electron..and also it is harder to remove an electron from s than p
Thank you for your help
