The wave function

(\Psi)

of

2 \mathrm{~s}

is given by

\Psi_{2 \mathrm{~s}}=\frac{1}{2 \sqrt{2 \pi}}\left(\frac{1}{a_0}\right)^{1 / 2}\left(2-\frac{r}{a_0}\right) e^{-r / 2 a_0}

At

r=r_0

, radial node is formed. Thus,

r_0

in terms of

a_0

A
$r_0=a_0$
B
$r_0=4 a_0$
C
$r_0=2 a_0$
D
$r_0=\frac{a_0}{2}$
