Select the correct statement(s) among the following — Atomic Structure Chemistry Question

💡 Solution & Explanation

Probability is never strictly zero outside an orbital contour. For $l = n-1$ (no radial node), $r_{mp} = \frac{n^2 a_0}{Z}$. Average distance $\langle r \rangle$ decreases slightly for higher $l$ within the same $n$. S-orbitals are spherically symmetric, completely independent of angles. Therefore, correct answer is B, C, D.
