Development of the nuclear model

WebThe modern model of the atom. Today, scientists use an atomic model that has a central, positively-charged nucleus that contains: positively-charged protons. neutral neutrons; WebIn 1808, John Dalton (1766 – 1844) proposed his atomic theory, which served as an explanation for these phenomena. His theory consists of five postulates. The first postulate states that all matter is composed of atoms. Second, the atoms of a given element are all exactly the same in structure and properties.
