The variation of radial probability density `R^2` (r) as a function of distance r of the electron from the nucleus for 3p orbital:

Represent graphically, the variation of probability density (psi^2 _(r)) as a function of distance (r ) of the electron from the nucleus for 1s and 2s orbitals.

Statement 1 : The plots of probability density and radial probability function versus distance r from the nucleus for any particular orbital are not identical, Statement 2 : Probability density is psi^(2) whereas radial probability function represents probability of finding the electron in a shell of thickness dr.

R(r) is the radial part of the wave function and r is the distance of electron from the nucleus.

For which of the following orbitals is the radial probaility density R^(2) the maximum at the nucleus and descrease sharply as the distance form the nucleus increases?
