Which statements are correct?
(a) \( \psi \) (orbital wave function) a mathematical function of co-ordinates of the electron.
(b) \( \psi^{2} \) represents probability density of electron at a point.
(c) Schrodinger wave equation play same role in quantum mechanism as Newtons Law of motion do in classical mechanism.
(d) Radial probability density \( \left[\mathrm{R}^{2}(\mathrm{r})\right] \) is maximum close to nucleus but total probability is least.
