WebWhen a radioactive nucleus gives off alpha or beta particles, it is in the process of changing into a different nucleus--a different element, or a different isotope of the same element. For example, radioactive thorium is formed when uranium-238--an isotope of uranium with 92 protons and 146 neutrons--emits an alpha particle.
