Question

The wave function $(Ψ)$ of $2 s$ is given by:
$Ψ_{2 s} = \frac{1}{2 \sqrt{2 π}} {(\frac{1}{a_{0}})}^{\frac{1}{2}} {2 - \frac{r}{a_{0}}} e^{- \frac{r}{2 a_{0}}}$
At $r = r_{0}$ , radial node is formed. Thus for $2 s$ , $r_{0}$ in terms of $a_{0}$ is:

r_{0} = a_{0}

Solution

The correct option is B $r_{0} = 2 a_{0}$
At the node, probability of finding an electron is zero. So, the wave function becomes zero.
When $r = r_{0}, ψ_{2 s} = 0$ , then from the given equation:
$2 - \frac{r}{a_{0}} = 0$
$r = 2 a_{0}$

The wave function (Ψ) of 2s is given by: Ψ2s=12√2π(1a0)12{2−ra0}e−r2a0 At r=r0, radial node is formed. Thus for 2s, r0 in terms of a0 is:

The correct option is B r0=2a0At the node, probability of finding an electron is zero. So, the wave function becomes zero. When r=r0, ψ2s=0, then from the given equation: 2−ra0=0 r=2a0
