Bohr radium for the hydrogen atom (n=1) ...

Bohr radium for the hydrogen atom (n=1) is approximately 0.530 Å. The radius for the first excited state (n=2) is (in Å)

A

`1.06 Å`

B

`0.265 Å`

C

`0.17 Å`

D

`0.53 Å`

Text Solution

Verified by Experts

The correct Answer is:
C
`r_(Li^(2+)) = (0.53)/(2) = (0.53)/(3) ~~ 0.17 Å`.
