The wave function of atomic orbital of H...

The wave function of atomic orbital of H-like atom is `R_(2,0) or R_(2s)=(1)/(4sqrt(2pi)) Z^(3//2) (2-Zr) e^(Zr//2)`
Given that the radius is in Å, then what is the radius for nodal surface for `He^(+)` ion.

A

1.75

B

1.5

C

1

D

0.5

Text Solution

Verified by Experts

`2-Zr=0. " "` Since Z = 2 for `He^(+)`, Zr = 2
`r=2//Z=2//2=1` au (atomic unit of radius).
