Energy is given out when one mole of gaseous magnesium ions is hydrated. Mg"(g) + aq → Mg"(aq) This is more exothermic than the corresponding value for barium ions, Ba", because the A ionic radius of Mg is less than that of Ba". B ionisation energy of magnesium is greater than that of barium. E C lattice energy of magnesium oxide is more exothermic than that of barium oxide. O D solubility of magnesium hydroxide in water is less than that of barium hydroxide.

For the following question , I did not get why is the correct answer  'A'

 

Energy is given out when one mole of gaseous magnesium ions is hydrated. Mg"(g) + aq -→ Mg (aq) This is more exothermic than the corresponding value for barium ions, Ba", because the A ionic radius of Mg is less than that of Ba". B ionisation energy of magnesium is greater than that of barium. C lattice energy of magnesium oxide is more exothermic than that of barium oxide. D solubility of magnesium hydroxide in water is less than that of barium hydroxide.
