WebE 1 = -13.6 eV. Hence, the minimum energy required to free an electron from the ground state of an atom is 13.6 eV. This energy is the ‘Ionization Energy’ of the hydrogen atom. This value agrees with the experimental value of ionization energy too. Now, a hydrogen atom is usually in ‘Ground State’ at room temperature. WebSep 24, 2024 · The Bohr Model is a modification of an earlier atomic model, the Rutherford Model.
