The ground state energy of hydrogen atom...

The ground state energy of hydrogen atom is `-13.6 eV`. The energy of second excited state of `He^(+)` ion in eV is

Text Solution

Verified by Experts

The correct Answer is:
`-6.04`
According to Bohr.s model energy in nth state
`=-13.6 xx Z^(2)/n^(2) eV`
For second excited state, of `He^(+)`, n=3
`therefore E_(3)(He^(+)) = -13.6 xx 2^(2)/3^(2) eV=-6.04`e V
