Document Summary
Nuclear structure nucleons protons neutrons mass number total number of nucleons isotopes same element but different mass number. Mostly unstable radioactive isobars same mass but different number of neutrons and protons. Fz of mass of carbon useful for energy to mass conversion. R = radius nucleons nucleons nuclear are are matter incompressible constant size tightly. Has packed a constant density of f- 2 stability nuclei cluster close to line of stability are no stable nuclei with. 16 are stable grows larger than increases the the number of neutrons number of protons when needed. Energy - energy nucleons needed to disassemble a nucleus into much mass larger nucleons than mass number in. Mev ) t mass number strong force: protons should repel each other due to electrostatic force, must be another force stronger than repulsive electrostatic force properties of strong force attractive force between doesn"t interact with any electrons. 2 nucleons short strong range force force is equal between any.
