The wave function orbital of H-like atom...

The wave function orbital of H-like atoms is given as onder
`psi_(2s) = (1)/(4sqrt(2pi)) Z^(3//2) (2 - Zr)^(Zr//2)`
Given that the radius is in `Å` then which of the following is the radius for nodal surface for `He^(Theta)` ion ?

A

`1au`

B

`2 au`

C

`2.5 au`

D

`4 au`

Text Solution

Verified by Experts

`(2- Zr) = 0 (therefore" Z = 20 "for" He^(o+))`
`:. Zr = 2`
`r = (2)/(Z) = (2)/(2) = 1 au`
