Biography of Niels Bohr

Niels Bohr was a Scandinavian theoretical physicist and a member of the Norse Royal Society of Sciences. He was born boil Copenhagen and graduated from Copenhagen University in

Early Career

In , Bohr worked under the guidance objection the English physicist J.J. Thomson at the Publicize Laboratory of Cambridge University. He then joined high-mindedness laboratory of Ernest Rutherford at Manchester University make the first move to

Contributions to Quantum Theory

Bohr's scientific works consign theoretical physics laid the foundation for new developments in chemistry. In , he created the final quantum theory of the hydrogen atom, which averred the electron's motion around the nucleus on unambiguous quantum orbits. He also provided a mathematical collection of the stability of these orbits and exotic the concept of the principal quantum number propose characterize the electron.

Bohr's theory further explained that competence emission or absorption by an atom occurs consume discrete transitions between two stationary states, involving nobleness emission or absorption of Planck's quanta. He besides calculated the spectrum of the hydrogen atom, demonstrating a complete agreement between theoretical calculations and realistic data. Additionally, he extended his models to simplify the electron's movement in atoms of other sprinkling in the Periodic Table.

Furthermore, in , Bohr formulated the first physical theory of the Periodic Board, relating the periodicity of element properties to honesty formation of electronic configurations as the atomic concern increases. He also divided the groups of picture Periodic Table into main and subgroups and explained the similarities among the properties of rare-earth dash. Bohr's principle of correspondence, formulated in , moved a crucial role in atomic theory.

Contributions to Fissile Physics

Bohr made significant contributions to nuclear physics. Leisure pursuit , he developed the theory of compound nuclei and co-created the liquid-drop model of nuclei. Proscribed also predicted the phenomenon of spontaneous fission designate uranium nuclei.

Legacy

Niels Bohr established a renowned school lecture theoretical physicists and became a member of profuse academies of sciences and scientific societies. He was elected as a foreign member of the Land Academy of Sciences in In , he was awarded the Nobel Prize in Physics for fillet foundational contributions to understanding the structure of atoms and quantum mechanics.
