This document contains a nuclear physics quiz asking about subatomic particles, atomic structure, radioactive decay, and radiation. It asks students to identify the charge of electrons and protons, define atomic number and isotopes with examples, list the atomic numbers of several elements, identify stable elements, forces acting in the nucleus, why the nucleus does not collapse, define radioisotopes, name types of radiation, determine the least ionizing and most penetrating radiation, give uses of radioactive sources, and ways to reduce radiation exposure.
