What is the reason why protons and electrons do not collide? Is email scraping still a thing for spammers. The few alpha particles that were deflected back or to one side were being repelled by nuclei, which are also positively charged. Therefore, scientists set out to design a model of what they believed the atom could look like. As the positively charged alpha particle would fly through the foil it would come in proximity with the positively charge nucleus of the atom. Describe Rutherford's model of the atom, including the location of protons, neutrons, and electrons with respect to the nucleus. PTIJ Should we be afraid of Artificial Intelligence? The goal of each atomic model was to accurately represent all of the experimental evidence about atoms in the simplest way possible. Since alpha particles which are relatively denser, were deflected by the central volume of charge, it shows that almost the complete mass of the atom must be within the central volume. He argued that the plum pudding model was incorrect. He concluded that all of the positive charge and the majority of the mass of the atom must be concentrated in a very small space in the atom's interior, which he called the nucleus.
