Which of the following is/are true information(s)? — Atomic Structure Chemistry Question

💡 Solution & Explanation

3s is spherically symmetric and has $3-0-1 = 2$ radial nodes. $d_{x^2-y^2}$ has lobes along X and Y axes. Maxima in radial probability = $n - l = 1, 2, 3$ respectively. $3d_{z^2}$ has a central doughnut-shaped region of electron density in the XY-plane, so it is not zero. Therefore, correct answer is A, B, C.
