Demonstrate how the mass of a stable nucleus is always less than the sum of the masses of the protons and neutrons comprising it. Know this is especially true of the elements in the region of the periodic table around iron (26 protons, 30 neutrons) and generally less so of elements with greater or lesser atomic numbers than this.
- Nuclear Processes
Nuclear processes are those in which an atomic nucleus changes; they include radioactive decay of naturally occurring and man-made isotopes and nuclear fission and fusion processes. As a basis for understanding this concept, students:
