The energy of an excited H-atom is -3.4e...

The energy of an excited H-atom is `-3.4eV`. Calculate angular momentum of `e^(-)`

Text Solution

Verified by Experts

If given energy is corresponding to the nth state of the atom, then
`E=-13.6/(n^(2))`
or `-3.4=(-13.6)/(n^(2))`
`:.n=2`
The angular momentum for n=2
`L=2(h/(2pi))=h/(pi)`
`=6.63/(pi)xx10^(-34)=2.11xx10^(-34)J-s`
