Question

why fall in inoziation energyoccur at Al ans S in same period​

Answer 1

Explanation:

Ionization energy generally increases across period 3 because the nuclear charge increases but the shielding of the outer electrons remains relatively the same. ... The first is between Mg and Al, because the outer electron of Mg is in the orbital 3s, whereas that of Al is in 3p.
