WebIn the third part of Dalton's atomic theory, he proposed that compounds are combinations of two or more different types of atoms. An example of such a compound is table salt. Table salt is a combination of two separate elements with unique physical and chemical properties. The first, sodium, is a highly reactive metal. 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.

Step 3: Third postulate, The energy of the outer orbit is greater than the inner orbit. when electron jump from an orbit to another there is energy difference which is equal to, WebBOHR solved the problem in 1913 by introducing postulates (casually: “by decree”) by transferring to the atom the quantization introduced by PLANCK for the black body and by EINSTEIN for the photon. However, it should be noted at this point that his third postulate (quantum condition) is no longer tenable from today’s perspective.
