Among the following, select the correct information(s) — Atomic Structure Chemistry Question

💡 Solution & Explanation

The opposite lobes in d-orbitals have matching signs. The 1s orbital wave function is entirely positive and independent of angles. Total nodes is always $n-1$, which is constant for a given orbit $n$. Radial nodes are not always greater than angular nodes (e.g., 3d has 0 radial and 2 angular). Therefore, correct answer is A, B, D.
