There was a problem. Atoms are so tiny that it was impossible to actually see inside them, especially back in the early 1900's. Is the Coronavirus Crisis Increasing America's Drug Overdoses? Bohr did not discover the model, he proposed it. In 1922, he was awarded the Nobel Prize in Physics for recognition of his work on the structure of atoms and quantum mechanics. Bohr went above and beyond the current theory of liquid surface tension by taking into account the viscosity of the water as well as incorporating finite amplitudes rather than infinitesimal ones. Here is an excerpt from one. He submitted his essay at the last minute, winning first place and a gold medal. He was born Niels Henrik David Bohr on October 7, 1855, in Copenhagen. Fact Check: What Power Does the President Really Have Over State Governors? and there are people who know the … 1. History. He also determined how many electrons were allowed on each energy level by giving the energy levels numbers. In 1913, Niels Bohr a danish physicist noticed that certain elements gave off certain colors when heated he thought that when the elements were heated the electrons got extra energy and jumped from a closer location to the nucleus to a place farther away from the nucleus. He invented the ‘Bohr Model’, and though it was not completely correct originally, scientists eventually refined the theory to make it 100 percent accurate. WILL GIVE BRANLIEST TO BEST ANSWER!!!
