Which of the following is the correct plot for the probability density \mathrm{\Psi^{2}(r)} as a function of distance 'r' of the electron from the nucleus for 2s orbital?

Option: 1


Option: 2


Option: 3


Option: 4

For 2s Orbital,

\mathrm{n=2,~\ell=0}

Number of radial nodes

\mathrm{=n-\ell-1}

\mathrm{=2-0-1=1}

And value of  \mathrm{\psi^{2}} is always positive.

So the plot of \mathrm{\psi^2 ~vs ~r} is 

Hence the correct option is 2.
