Question

Formula to find energy difference between.Ground state and first excited state of a electron

Answer 1

Energy difference between ground state and first excited state

Because an electron bound to an atom can only have certain energies the electron can only absorb photons of certain energies exactly matched to the energy difference, or “quantum leap”, between two energy states. ... For example an electron in the ground state has an energy of -13.6 eV. The second energy level is -3.4 eV.
