Choose the correct statements from the following.

Node is the point in space at which wave-function has no or 0 value. Thus, ψ has 0 amplitude. The number of maxima (peaks) in radial distribution in n−l.

ψ2 shows the probability of getting electron and $4{\mathrm{\pi r}}^2{\mathrm{R}}_{\mathrm{n},\mathrm{l}}^2\left(\mathrm{r}\right)$  represent the radial probability.
