Concept Review 3.1 Introduction to Nuclear
... Strong Force – holds the protons and neutrons (nucleons) together in a nucleus, resisting the positive protons from repelling each other as long as these particles are very close together. Beyond the atomic number 83 (Bismuth), the repulsive force of the protons is so great that no stable nuclides ...
