Select the correct statement(s):
A. Radial function `[R(r)]` a part of wave function is dependent on quantum number n only
B. Angular function depends only one the direction, and is independent to the distance from the nucleus
C. `psi^(2)(r, theta,phi)` is the probability density of finding the electron at a particular point in space
D. Radial distribution function `(r^(2)R^(2))` gives the probability of the electron being present at a distance r from the nucleus
