How does radioactivity create a new element

WebRadioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.A material containing unstable nuclei is considered radioactive.Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma … WebA more efficient approach is to artificially manufacture radioisotopes. This can be done by firing high-speed particles into the nucleus of an atom. When struck, the nucleus may absorb the particle or become unstable and emit a particle. In either case, the number of particles in the nucleus would be altered, creating an isotope.
