Which of the following graph represents the radial probability function of 3d electron? — Atomic Structure Chemistry Question

💡 Solution & Explanation

The number of radial nodes for a 3d orbital is given by $n - l - 1 = 3 - 2 - 1 = 0$. A graph of the radial probability function $4\pi r^2 R^2$ vs $r$ with zero radial nodes will have exactly 1 distinct peak without crossing the x-axis before dropping to zero at infinity. Option (a) shows 1 peak. Therefore, correct answer is A.
