Following the discovery of the electron in 1897 by Joseph John Thomson , it was determined that the material consisted of two parts, one negative and a positive. The downside was made up of electrons, which according to this model were immersed in a mass of positive charge by way of raisins in a cake (from the analogy of English plum-pudding model).
Details of the atomic model
To explain the formation of ions, both positive and negative, and the presence of electrons within the atomic structure, Thomson devised an atom like a fruitcake. A cloud containing small positive negative particles (electrons) suspended in it. The number of negative charges was inadequate to neutralize the positive charge. In the event that the atom loses an electron, the structure would be positive, and if he won, the final charge would be negative. Thus, explaining the formation of ions, but left without explanation the existence of the other radiations.
