If the radius of the first Bohr orbit of...

If the radius of the first Bohr orbit of the H atom is r then for the `Li^(2+)` ion it will be:

A

`3r`

B

`9r`

C

`r//3`

D

`r//9`

Text Solution

Verified by Experts

The correct Answer is:
C
`r_(n) prop (n^(2))/(z)-((r)_(H))/((r)_(Li^(2+)))=(Z_(Li^(2+)))/(Z_(H))-r_(Li^(2+))=(r)/(3)`
