The number of radial and angular nodes for the orbital is, respectively, — Atomic Structure Chemistry Question

💡 Solution & Explanation

Angular nodes are determined by the angular component $\cos\theta$, which corresponds to $l=1$ (1 angular node). Radial nodes correspond to the non-zero roots of the radial polynomial $(\sigma-1)(12-8\sigma+\sigma^2)$. The roots are $\sigma = 1, 2, 6$. Thus, there are 3 radial nodes. Therefore, correct answer is A.
