WebSep 16, 2024 · The solar system or planetary model of the atom was attractive to scientists because it was similar to something with which they were already familiar, namely the solar system. Figure 9.4. 3: Niels Bohr with Albert Einstein at Paul Ehrenfest's home in Leiden (December 1925). Unfortunately, there was a serious flaw in the planetary model. WebBohr proposed the Bohr model which is more often known as the planetary model or the solar system model. This model was very different from others, as it showed that there were layers of electrons that orbit the atomic nucleus. However, the model also showed that the electrons could jump from each energy level. WebMar 22, 2024 · Plum Pudding and Bohr Models.
