The Bohr model of the atom,the theory that electrons travel in discrete orbits around the atom’s nucleus. What was Niels Bohr contribute to chemistry? Niels also worked out the problem in the atom’s structure. He was on of the main physicists to form the first ever atomic bomb during World War II (Manhattan Project). What was Niels Bohr’s major accomplishment? Bohr introduced the theory that electrons travel in an orbital path around the atom’s nucleus. Niels Bohr was a Danish scientist who won the Nobel Prize for physics in 1922 for his work in regards to understanding the structure of atoms. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump. To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. How does Bohr’s theory help to solve the discrepancies of Rutherford’s theory? He found that the ratio of energy in electrons and the frequency of their orbits around the nucleus was equal to Planck’s constant (the proportion of light’s energy to its wave frequency, or approximately 6.626 x 10-23 ). How quantum theory helped Bohr to explain the stability of an atom?īohr turned to Planck’s quantum theory to explain the stability of most atoms. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus. What was Niels Bohr’s most important discovery? Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation.
In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. What did Bohr contribute to the atomic theory? Bohr’s model explained why atoms only emit light of fixed wavelengths, and later incorporated the theories on light quanta. Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.
