Chemistry Agumentative Essay

The Bohrs atomic Model Argumentative Essay shhss In 1913, a Danish physicist named Niels Bohrput Rutherfords findings to workher with the observed spectra to semen up with a new exemplification of the atom in a real leap of intuition. I believe that the Bohrs model of atom explains well ab erupt the atomic theory, because in his experiments it is shown and explained the structure of an atom. His far-famed suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented with atomic spectrum that proved his suggestion.The Bohrs experiments with atomic spectra explained how to each whiz element had a unique spectrum and thewavelengthof each line within a spectrum had a specific life force. When atoms in the gas tubes absorbed the energy from the electric current, the electrons became excited and jumped from low energy levels (close to the nucleus) to high energy levels (farther out from the nucleus). The excited electrons would fall back to their ori ginal levels and emit energy as light. Because there were specific differences mingled with the energy levels, only specific wavelengths of light were seen in the spectrum.Bohrs Periodic behavior of elements described how did elements with standardized properties had similar atomic spectra. Bohr also explained that Each electron orbit of the same size or energy (shell) could only intimidate so many electrons. For example, the first shell could hold two electrons, the second 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. Chemical 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 model is also useful for explaining the behavior oflasers, although these devices were not invented until the middl e of the 20th century. Bohrs model was the model that made a great leap 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.
