N a+ has stable electronic configuration (1s2,2s22p6). If remove extra electrone that is present in inner shell, so need more energy to remove it.(insufficient amount of energy)

Q. Which of the following processes requires maximum energy

$M g (g) \to (M g)^{+} (g) + e^{-}$

$(M g)^{+} (g) \to (M g)^{+ 2} (g) + e^{-}$

$N a (g) \to (N a)^{+} (g) + e^{-}$

$(N a)^{+} (g) \to (N a)^{2 +} (g) + e^{-}$

$N a^{+}$ has stable electronic configuration (1s²,2s²2p⁶). If remove extra electrone that is present in inner shell, so need more energy to remove it.(insufficient amount of energy)

Q. Which of the following processes requires maximum energy

Mg(g)→(Mg)+(g)+e−

(Mg)+(g)→(Mg)+2(g)+e−

Na(g)→(Na)+(g)+e−

(Na)+(g)→(Na)2+(g)+e−

Na+ has stable electronic configuration (1s2,2s22p6). If remove extra electrone that is present in inner shell, so need more energy to remove it.(insufficient amount of energy)
