The radius of the innermost electron orb...

The radius of the innermost electron orbit of a hydrogen atom is `5.3 xx 10^(–11) m`. What are the radii of the n = 2 and n =3 orbits?

A

`R_(2)=2.12xx10^(-11)m,R_(3)=4.77Å`

B

`R_(2)=2.12xx10^(-10)m,R_(3)=4.77Åxx10^(-11)m`

C

`R_(2)=2.12Å,R_(3)=4.77Å`

D

`R_(2)=2.12xx10^(10)Å,R_(3)=4.77xx10^(-10)Å`

Text Solution

Verified by Experts

The correct Answer is:
C
`R_(2)=2.12Å,R_(3)=4.77Å`
