If nucleus and atom are considered as perfect spheres with the diameters 4 * 10^-15 m and 2 * 10^-10 — Atomic Structure Chemistry Question
Question
If nucleus and atom are considered as perfect spheres with the diameters 4 * 10^-15 m and 2 * 10^-10 m, respectively, then the ratio of the volumes of nucleus and atom should be
Answer: B
💡 Solution & Explanation
Volume ∝ d^3. V_nucleus/V_atom = (4*10^-15 / 2*10^-10)^3 = (2*10^-5)^3 = 8*10^-15.
