Probability density is given by

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.

Probability density curve for 3s orbital

Statement -I : Probability density of electron is zero at nucleus for all p & d orbitals. Statement -II : Probability density of electron at the nucleus depends upon azimuthal quantum number only.
