Niels bohr atomic theory3/1/2024 ![]() ![]() He proposed his own atomic model, the theory of the composite nucleus, the liquid drop theory and worked in the. Understanding Bohr's model requires some knowledge of electromagnetic radiation (or light).īohr's key idea in his model of the atom is that electrons occupy definite orbitals that require the electron to have a specific amount of energy. Niels Bohr is a physicist that is know for his contributions to quantum physics. In 1913, the Danish physicist Niels Bohr proposed a model of the electron cloud of an atom in which electrons orbit the nucleus and were able to produce atomic spectra. These difficulties cast a shadow on the planetary model and indicated that, eventually, it would have to be replaced. Das Bohrsche Atommodell ist das erste weithin anerkannte Atommodell, das Elemente der Quantenmechanik enthält. The classic diagram of the atom depicts a small. Furthermore, Rutherford's model was unable to describe how electrons give off light forming each element's unique atomic spectrum. March 6, 1913: Bohr describes his model of atom to Rutherford. If the electron circling the nucleus in an atom loses energy, it would necessarily have to move closer to the nucleus as it loses energy, and would eventually crash into the nucleus. Atom - Bohrs Shell Model: In 1913 Bohr proposed his quantized shell model of the atom (see Bohr atomic model) to explain how electrons can have stable orbits around the nucleus. This is, after all, how we produce TV signals. ![]() ![]() It was already known that when a charged particle (such as an electron) moves in a curved path, it gives off some form of light and loses energy in doing so. Unfortunately, there was a serious flaw in the planetary model. Born: October 7, 1885, Copenhagen, Denmark Died: November 18, 1962, Copenhagen (aged 77) Awards And Honors: Copley Medal (1938) Nobel Prize (1922) Notable Family Members: son Aage N. \): Niels Bohr with Albert Einstein at Paul Ehrenfest's home in Leiden (December 1925). ![]()
