For centuries upon centuries, humans have developed ideas based on their experimental findings. Due to the fluidity of science, these ideas have been through many stages before the most plausible one is decided upon. Atomic theory began with Greek philosophers in Ancient times and carried over to modern science. The knowledge acquired by past scientists has had a great impact on discoveries made by those that followed. Furthermore, the models of the atom that Ernest Rutherford and J.J. Thomson proposed have definitely enhanced my Bohr model. Thomson’s “plum pudding model” was a pivotal pre-requisite to many updated models of the atom, for it incorporated the, recently discovered, electron. This only preceded Rutherford’s more accurate model, which conveyed that these electrons had a specific location relative to the rest of the atom. In my Bohr model, it is depicted that these very subatomic particles follow a specific circular orbit and can shift its path depending on the present conditions. Though the location and presence of the electron varies between models, all versions of it have information that holds true throughout. Aside from the negatively charged region to which the electrons belonged, the other major part of the atom is positively charged. J.J. Thomson’s model recognized most of the atom as positively charged with the occasional electron to balance the charge out. As a result of Rutherford’s gold-foil experiment, his model isolated the positive charge in a region unique to that of the electrons. The positively charged region was thus coined the “nucleus” of an atom, which was featured as the central point of my atomic model. This even further proves the point that each model of the atom supplies information for their subsequent relatives. Some may say that the models of the atom only replace each other, but this is not true. Every model leading up to the next
