Given below are some statements regarding atomic structure: A. Isobars are atoms of different elements having the same mass number. B. The atomic number of an element is equal to the number of neutrons present in its nucleus. C. All isotopes of a given element possess the same number of protons. D. Cathode rays consist of positively charged particles. E. The mass of a neutron is slightly greater than the mass of a pr

Step-by-step solution

Statement A is correct. Isobars are atoms of different elements that have the same mass number but different atomic numbers. Statement B is incorrect. The atomic number of an element is equal to the number of protons present in its nucleus, not the number of neutrons. Statement C is correct. Isotopes of a given element have the same atomic number, which means they possess the same number of protons, but they differ in the number of neutrons. Statement D is incorrect. Cathode rays consist of electrons, which are neg
