radioactive elements are elements that are considered unstable due to the unbalanced number of neutrons and protons in the nucleus.
an element subject to spontaneous degeneration of its nucleus accompanied by the emission of alpha particles, beta particles, or gamma rays. All elements with atomic numbers greater than 83 are radioactive. Naturally occurring radioactive elements include radium, thorium, anduranium.
