Structures of nuclei of three atoms A, B and C are given below: A has 90 protons and 146 neutrons. B has 92 protons and 146 neutrons. C has 90 protons and 148 neutrons. Based on the above data, A and C are isotopes; B and C are
Isobars are atoms of different chemical elements that have the same number of nucleons. They differ in atomic number (or the number of protons) but have the same mass number.
Whereas an isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element. The nuclei of most atom s contain neutrons as well as protons.
