Web23 sep. 2024 · Here are the major postulates of Rutherford’s atomic model based on observations and conclusions: Positively charged particles make up an atom. The majority of an atom’s mass was contained in a very small area. The nucleus of an atom was the term used to describe this area of the atom. Later it was discovered that neutrons and … WebUsing these ideas, Bohr developed a conceptual model in which an electron moving around the nucleus is restricted to certain distances from the nucleus, with these distances determined by the amount of energy the electron has. Bohr saw this as similar to how the planets are held in orbit around the sun at given distances from the sun.
