The correct statement among the following

Options

A. A node is a point in space where the wave-funtion Y has zero amplitude .
B. The number of maximum (peaks) in radial probability distribution function is (n-l)
C. Radial probability density is `4pi r^2 R_(n.l)^2 (r)`
D. `Psi` represents probability of finding electron

Answer

A, B, C, D

Explanation

At node `Psi^2 = 0 `
number of radial nodes = n-l-1
nodes of peaks = n-1
