For the ground state of a hydrogen atom ( orbital), a plot of the radial probability distribution fu — Atomic Structure Chemistry Question

💡 Solution & Explanation

The radial probability distribution curve for the $1s$ orbital of hydrogen exhibits a single peak. The distance from the nucleus at which this peak occurs corresponds to the maximum probability of finding the electron. Quantum mechanics shows this distance ($r_{max}$) is exactly equal to the radius of the first Bohr orbit, known as the Bohr radius ($a_0 = 0.529 \text{ \AA}$).
