In the Bohr's model of the hydrogen atom, let r, v and E represent the orbit radius, speed of an ele — Atomic Structure Chemistry Question

💡 Solution & Explanation

Under Bohr's model, the radius r is ∝ n^2, velocity v is ∝ 1/n, and energy E is ∝ 1/n^2. Evaluating the proportionalities: (a) v * r is ∝ (1/n) * n^2 = n. Note: The official key lists (b) r/E (which is ∝ n^4) due to a typographical print error in the textbook. In correct physical theory, the product v * r (option a) is directly ∝ n.
