The orbits are labeled by the quantum number n.ġ2 Neils Bohr: Contributions to the Atomic Theory He concluded that because of this quantization, electron orbits have fixed sizes and energies. He hypothesized that the angular momentum of the electron is quantized (which means it only has discrete values). Bohr composed an accurate formula for the energy levels of a hydrogen atom using Planck’s constant. Using the Young’s slit device, Bohr delimited two quantum paths between the source and the detecting plane. Which explains the structure and complexity in the actions of atoms.

Later other physicists expanded his theory into quantum mechanics. He also concluded that these outer orbits can determine an atom's chemical properties, and that Atoms emit radiation and light when an electron jumps from an outer orbit to an inner one. Proposed that Atoms moved In fixed paths around the nucleus, like planets orbiting a sun.īohr concluded that the outer orbits could hold more electrons than the inner ones. Electrons orbit around the nucleus which contains the Neutrons and Protons. The Bohr model gave way to the theory of Atoms, which is called Quantum mechanics. 1962 Returned to Copenhagen and furthered studied nuclear energy.ĩ The Bohr Model The Bohr Model of the atom revealed some of the most important properties of molecular and Atomic structure.

Work on nuclear fission and created liquid droplet theory which described the way neutrons and protons behaved.ħ 1950’s In 1954, Neil assembled the Atoms for Peace Conference of In 1957, Bohr received the Atoms for Peace Award for his theories and examples to show how to use atomic energy responsibly. Quantum theory showed the specific relation proportion of an electron and how it circulates the atoms’ nucleusĥ 1922 Bohr received a Nobel Prize in Physics for work of 'for his services in the investigation of the structure of atoms and of the radiation emanating from them.' He continued to study new quantum principles which ultimately explained why light can be seen as a particle and wave but not at the same time He developed an explanation for atomic structure that uses the periodic table of elements.Ħ 1930 Neil clarified problems in quantum physics Also showed the light quantum of distinct energy, which formed the bases for the quantum theory. The model also purposed that electrons could drop from higher energy orbit to a lower orbit. This model proposed that electrons circled the atom’s nucleus in a certain way, therefore it also explained that electron traveled in specific energy.
