The ratio is maximum for — Atomic Structure Chemistry Question

💡 Solution & Explanation

The ratio is specific charge = $q/m$. For Na$^+$, it is $1/23$. For Al$^{3+}$, it is $3/27 = 1/9$. For H$^+$, it is $1/1$. For Mg$^{2+}$, it is $2/24 = 1/12$. The maximum ratio is for H$^+$. Therefore, correct answer is C.
