Study the information in the table below and answer the questions that follow.

(a) Explain why the ionic radius of K⁺ is greater than that of Na⁺
(b) Account for the difference in ionic radius of Mg²⁺ and Na⁺

---

(a) K⁺ has more energy levels than Na⁺
(b) Both are in the same period Na⁺ radius is larger than Mg²⁺ because additional electrons in Mg²⁺ are added to same energy level and there is increase in number of protons in the nucleus leading to more force of attraction between the protons and electrons making Mg²⁺ smaller than Na⁺.
