why certain isotopes of chemical elements become radioactive, and why they have varying half-lives
All things want to be stable. A nucleus is generally stable when it has the same number of neutrons and protons. If a nucleus isn't stable it will get rid of particles until it reaches a stable state.
The Short Answer
All things want to be stable. A nucleus is generally stable when it has the same number of neutrons and protons. If a nucleus isn't stable it will get rid of particles until it reaches a stable state. The release of particles is radiation, the type of radiation depends on the type of particles released. Half life depends on how stable a nucleus is. The more unstable it is, the shorter the half life and vice versa.
