Consider `psi` (wave function) of `2s` atomic orbital of H-atom is-
`psi_(2s)=(1)/(4sqrt(2pia_(0)^(3//2)))[2-(r )/(a_(0))]e^.(r )/(2a_(0)`
Find distance of radial node from nucleous in terms of `a_(0)`

A

`r=a_(0)`

B

`r=2a_(0)`

C

`r=a_(0)`

D

data insufficient

Text Solution

Verified by Experts

`R(r ) = 0`
`[2-(r )/(a_(0))]e^((r)/(2a_(0)))=0implies2-(r )/(a_(0))=0impliesr=2a_(0)`
