Nuclear Model Of The Atom Based on his observations and conclusions, Rutherford proposed his model of the structure of the atom. Despite the fact that the energies are essentially correct, the Bohr model masks the true quantum nature of the electron, which only emerges from a fully quantum mechanical analysis. Bohr model is associated with hydrogen line spectrum. What was the difference between Thomsons and Rutherfords models of the atom explain how Rutherford was able to refute Thomsons model? Later on, a physicist put forth another principle called Heisenbergs uncertainty principle, which explains the impossibility of the simultaneous determination of exact position and momentum of small moving particles such as electrons. Nearly a century later, Thomson introduced the newly discovered negatively charged electrons in his atomic model: with the "plum pudding mode,l" the atoms were finally divisible, but physicists were still a far shot from a realistic description of the atom. 6. Rutherford and Bohr proposed two different models for the atomic structure. (from science.howstuffworks.com) Bohr also said it but in a slightly modified way. Sign up for free to discover our expert answers. In the Bohr model, the electrons' orbits are at fixed discrete distances from the nucleus, and in the Rutherford model, the orbits vary in their distance from the nucleus. The first issue is the lack of emitted radiation: when subjected to an acceleration, a charged particle emits electromagnetic radiation at specific frequencies. Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element. It does not show that the atom has a nucleus. By clicking Accept All, you consent to the use of ALL the cookies.
