Question

Quizplus · Accepted Answer

Atomic isotopes have the same number of protons (and therefore the same chemical properties) but differ in the number of neutrons. This affects the atomic mass of the isotope but not its chemical behavior. Some isotopes can be unstable and emit radiation, but they are not necessarily produced by exposure to radiation.
