"the energy of an electron in the first bohr orbit oh h atom is -13.6eV .the possible energy value of the excited states for electrons in bohr orbits in hydrogen are
Energy for a hydrogen atom = -13.6/n2 where n is the orbit.
For n=1 E- -13.6 eV
For n=2, E = -13.6/4 = -3.4eV (option A)
For n=1 E- -13.6 eV
For n=2, E = -13.6/4 = -3.4eV (option A)
