what did bohr discover

In 1913 Bohr published a theory about the structure of the atom based on an earlier theory of Rutherford's. He was born Niels Henrik David Bohr on October 7, 1855, in Copenhagen. 1913. The electron in a hydrogen atom travels around the nucleus in a circular orbit. (1885–1962) Person. Quantized model. Bohr found that the closer an electron is to the nucleus, the less energy it needs, but the farther away it is, the more energy it needs. Start studying Niels Bohr. Numerically, the measure is close to the known size of atoms. Niels Bohr, in full Niels Henrik David Bohr, (born October 7, 1885, Copenhagen, Denmark—died November 18, 1962, Copenhagen), Danish physicist who is generally regarded as one of the foremost physicists of the 20th century.He was the first to apply the quantum concept, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. Bohr's model of atomic structure. Albert Einstein, often called the father of modern physics, is perhaps the best known scientist in the world. Bohr did not discover this. He invented the ‘Bohr Model’, and though it was not completely correct originally, scientists eventually refined the theory to make it 100 percent accurate. See answer blockhaiianton is waiting for your help. History of atomic structure Discovery of the electron and nucleus Points that agree with Rutherford’s postulates Bohr noticed, however, that the quantum constant formulated by the German physicist Max Planck has dimensions which, when combined with the mass and charge of the electron, produce a measure of length. [/caption]Niels Bohr was a Nobel Prize winner. So Bohr numbered the electron’s energy levels. What did they discover? Niels Bohr in 1922. Relevance. Scientists now know that the nucleus of the atom contains both positively charged protons and neutral neutrons, which have the same mass. The Chadwick atomic theory arose from James Chadwick's discovery of the neutron. Comment … Rutherford had shown that the atom consisted of a positively charged nucleus, with negatively charged electrons in orbit around it. Niels Bohr put forward his picture of the atom in 1913. Niels Bohr contributed to the foundational understanding of atomic structure and solved quantum theory. On January 26, 1939, during the Fifth Washington Conference on Theoretical Physics at the George Washington University, Nobel Laureate Niels Bohr publicly announced the splitting of the uranium atom. what did niels bohr discover. 1922. What was Bohr's model called? Electrons should move around the nucleus but only in prescribed orbits. Model of the Atom (Niels Bohr) In 1913 one of Rutherford's students, Niels Bohr, proposed a model for the hydrogen atom that was consistent with Rutherford's model and yet also explained the spectrum of the hydrogen atom. The higher the energy-level number, the farther away the electron is from the nucleus — and the higher the energy. A Nobel Prize Winner: Neils Bohr was a Danish physicist that lived from 1885 to 1962. His home atmosphere growing up aided his intellect and skill in … 3 Answers.
