The ratio of specific charges of -particle and deuteron is — Atomic Structure Chemistry Question

💡 Solution & Explanation

Specific charge = $q/m$. For $\alpha$-particle ($^4_2He^{2+}$), $q=2, m=4 \implies q/m = 1/2$. For deuteron ($^2_1H^+$), $q=1, m=2 \implies q/m = 1/2$. The ratio is $(1/2) : (1/2) = 1:1$. Therefore, correct answer is C.
