Question

Out of sodium and sodium which has smaller size and why

Answer 1

Answer:

Out of Na , Na⁺ ,

Na⁺ has a smaller size because it attains the nearest noble gas ie neon configuration

Na => 1s² 2s² 2p⁶ 3s¹

Na⁺ => 1s² 2s² 2p⁶

there is an absence of 3s subshell in Na⁺ and results in smaller size .
