Which of the following statements regarding nuclear chemistry is correct?

Question

Quizplus · Accepted Answer

A nuclide is defined as an atom with a specific atomic number (number of protons), mass number (number of protons plus neutrons), and neutron number (difference between mass number and atomic number). This distinguishes one nuclide from another and explains why certain nuclides may be radioactive due to an imbalance in the number of protons and neutrons, leading to instability. The other answer choices are incorrect - A is false because the majority of known nuclides are actually unstable and radioactive, B is false because there are trends and patterns in the stability of nuclides based on their proton and neutron numbers, D is false because a nucleon specifically refers to a proton or neutron (not an electron), and E is false because most elements have multiple isotopes (atoms with the same number of protons but different numbers of neutrons).
