WebSolution. Before the Discovery of Neutron the atomic mass of the elements was found to be double or more than double of the number of protons. Since, the mass of an electron is negligible, It was ambiguous about where the rest of the mass is coming from. For example, if we consider the Carbon atom mass number of Carbon is 12 but the number of ...

WebThe neutron–proton ratio ( N/Z ratio or nuclear ratio) of an atomic nucleus is the ratio of its number of neutrons to its number of protons. Among stable nuclei and naturally occurring nuclei, this ratio generally increases with increasing atomic number.
