Question

Give the increasing order of ionisation potential of Na , Mg , Al​. Also explain. Plzz quickly

Answer 1

ionization potential or ionization  energy is the amount of energy required to remove a electron from its outermost shell for a isolated gaseous atom

1)Na has lowest ionization potential  since its nuclear charge is less then the other 2
2)Mg
3)Al has highest nuclear charge ie nucleus attracts electrons the most therefore ionization potential  is the highest
