MCQ
Which ionisation potential $\left( {IP} \right)$ in the following equations involves the greatest amount of energy
  • A
    $Na \to N{a^ + } + {e^ - }$
  • ✓
    ${K^ + } \to {K^{2 + }} + {e^ - }$
  • C
    ${C^{2 + }} \to {C^{3 + }} + {e^ - }$
  • D
    $C{a^ + } \to C{a^{2 + }} + {e^ - }$
✓

Answer

Correct option: B.
${K^ + } \to {K^{2 + }} + {e^ - }$
b
(b)${K^ + } \to {K^{2 + }} + {e^ - }$. Since ${e^ - }$ is to be removed from stable configuration.
