1.	The wavefunction of a 2s electron is given by ψ2s=14√2π(1a0)32(2−ra0)e−ra0 It has a node at r=r0. The value of r0a0 is___
Answer» The wavefunction of a 2s electron is given by $ψ_{2 s} = \frac{1}{4 \sqrt{2} π} (\frac{1}{a_{0}})^{\frac{3}{2}} (2 - \frac{r}{a_{0}}) e^{\frac{- r}{a_{0}}}$ It has a node at $r = r_{0}$ . The value of $\frac{r_{0}}{a_{0}}$ is___
