'The BohrÃ¢â¬â¢s Atomic Model | Argumentative canvass| shhss| In 1913, a Danish physicist named Niels BohrÃÂ beat Rutherfords findings together with the observed spectra to come up with a new copy of the element in a real bound of intuition. I believe that the BohrÃ¢â¬â¢s place of atom explains well about the atomic theory, because in his experiments it is shown and explained the structure of an atom. His famous pinch is about that the electrons orbit around the effect of an atom. Bohr experimented with atomic spectrum that proved his suggestion.The BohrÃ¢â¬â¢s experiments with atomic spectra explained how each element had a unparalleled spectrum and theÃÂ wavelengthÃÂ of each line within a spectrum had a specific pushing. When atoms in the gunman tubes absorbed the pushing from the electric current, the electrons became turned on(p) and jumped from low energy levels (close to the nucleus) to high energy levels (farther out from the nucleus). The excited elect rons would fall ass to their original levels and emit energy as light. Because there were specific differences between the energy levels, unless specific wavelengths of light were seen in the spectrum.BohrÃ¢â¬â¢s Periodic behavior of elements set forth how did elements with similar properties had similar atomic spectra. Bohr in like manner explained that Each electron orbit of the selfsame(prenominal) size or energy ( work over) could only consider so many electrons. For example, the freshman shell could hold two electrons, the number could hold eight electrons, the third could hold 18 electrons, the fourth 32 and so on until reaching the seventh. When one shell was filled, electrons were found at higher levels. chemic properties were based on the number of electrons in the outermost shell.Elements with full outer shells do not react. Other elements take or give up electrons to get a full outer shell. As it turns out, Bohrs position is also useful for explaining the beh avior ofÃÂ lasers, although these devices were not invented until the middle of the 20th century. Bohrs model was the model that made a great climb up in sciences until new discoveries were made. This model was proposed in 1913 by Niels Bohr and was really an expansion on the Rutherford model of 1911. The Rutherford model had several flaws that the Bohr model overcame.\r\n'
