Radioactivity is the process by which an unstable atomic nucleus loses energy through radiation. The most common types of radiation are alpha, beta, and gamma, but other types of radioactive decay include proton emission, neutron emission, and spontaneous fission of large nuclei.  Here are some examples of radioactive decay: Alpha decay: An atomic nucleus emits an alpha particle (helium nucleus), which transforms the nucleus into a different atomic nucleus with a mass number reduced by four and an atomic number reduced by two Beta decay: A beta ray is emitted from an atomic nucleus,...
