Question

The ground state and first excited state energies of hydrogen atom are $-13 \cdot 6 eV$ and $-3.4 eV$ respectively. If potential energy in ground state is taken to be zero. Then :

(a) P.F. in the first excited state would be $10 \cdot 2 cV$

(b) total encrgy in the first excited state would be $23 \cdot 8 eV$

(c) K.I : in the first excited state would be $10.2 cV$

(d) Total encrgy in the ground would be $17 \cdot 0 eV$

Answer 1

ANSWER : Here, the correct answer of this question will be option (B) which is — total energy in the first excited state would be $23 \cdot 8 eV$
