Each electron in an atom is in an orbital (*NOT* an orbit!!) at a specific energy level from the positive nucleus. The energy levels of these orbitals are fixed -- an electron can go from orbital 's' to orbital 'p', but it can't go halfway between these two orbitals. When an electron in an atom goes from a higher orbital to a lower one, then the atom must give off an amount of energy, that is exactly the difference in energy in the two levels.
For a hydrogen atom, these orbital levels are fixed by the fact that the angular momentum of an electron in an orbital is quantized -- ie, it comes in exact multiples, but not fractions, of a minimal amount.
Based on conversations with Rutherford Niels Bohr developed the Bohr-Rutherford nuclear model of the Atom. It is the one you have met in elementary school where Protons and Neutrons form a core with electrons circling in fixed orbits around the core. The orbits explained (some kind of) radiation which had hitherto been a mystery. He discovered that electrons in atoms are arranged according to the energy levels.
Niels Bohr is best known for his work on the quantization of atomic structure, particularly his model of the atom which proposed that electrons orbit the nucleus in specific, quantized energy levels. While he conducted thought experiments and made theoretical contributions that shaped the field of quantum mechanics, he did not perform specific physical experiments in a laboratory setting.
Niels Bohr was famous for his contributions to the development of quantum theory. He proposed the model of the atom with electrons orbiting the nucleus in quantized energy levels, known as the Bohr model. Bohr also made important contributions to our understanding of nuclear structure and the principle of complementarity in quantum mechanics.
He proposed a description of the structure of atoms, especially that of hydrogen in 1913. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.He said that atom consists of a heavy positively charged nucleus with substantially lighter negatively charged electrons circling around it at considerable distance.He predicted that element 72 would behave as he thought. The element was named hafnium (Latin for Copenhagen).He worked with others to develop the atomic bomb, he made significant technical contributions, notably to the design of the so-called initiator for the plutonium bomb.
Niels Bohr (the father, not the son who also got a Nobel prize) is known for: - Nuclear models with layers explaining radiation - Contributions to quantum mechanics - Political work after WWII to put the nuclear bomb under UN control
Niels Bohr worked in the field of physics, with a focus on atomic structure and quantum theory. He made significant contributions to the development of the theory of quantum mechanics and is best known for his model of the atom, called the Bohr model.

Niels Bohr was a Danish physicist who made significant contributions to our understanding of atomic structure and quantum theory. He is best known for proposing the Bohr model of the atom, which introduced the idea of electrons orbiting the nucleus in specific energy levels. This model laid the foundation for modern quantum mechanics and earned him the Nobel Prize in Physics in 1922.
In 1938 Bohr worked with Albert Einstein and carried out atomic research; was elected president of the Danish Academy of Science and was an advisor to the Manhattan Project, which produced the first atomic bomb.

The Bohr model fails to fully explain the behavior of atoms with more than one electron, as it simplifies the complex interactions in multi-electron systems. It also does not account for the concept of electron spin or the shape of atomic orbitals.
James Chadwick is best known for discovering the neutron in 1932, which significantly contributed to the understanding of atomic structure. While he did not propose a specific atomic model like the Bohr model, his discovery led to the development of the nuclear model of the atom, which incorporates protons and neutrons in the nucleus, surrounded by electrons in orbit. This model laid the groundwork for modern quantum mechanics and nuclear physics.
