Rutherford imagined a planetary model of an atom but it had a mechanical drawback. Rutherford deduced that Atom comprised of a diffuse cloud of negatively charged electrons that surrounded a tiny, dense, positively charged nucleus in the early 20th century. Rydberg’s observation can be seen in Bohr’s theory as the description of the energies of transitions or quantum jumps between orbital energy levels. The success of the Bohr’s Atomic Model lies in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen. The improvement done to Rutherford’s Model is mainly a quantum physical interpretation of the model.
What is Neil Bohr’s Atomic ModelĪccording to Niels Bohr, his Atomic Model explained the existence of an Atom which consists of a small, dense Nucleus which is surrounded by orbiting electrons much like the structure of the Solar System, where the attraction between the particles is due to electrostatic force rather than gravity.įig. This post will discuss about what is Neil Bohr’s Atomic Model, how it different from Rutherford’s Atomic Model, its three postulates and limitations.
Neil Bohr’s Atomic Model is an improvement of Rutherford’s Atomic Model and was presented by both Niels Bohr and Ernest Rutherford in 1913.
