Radioactive decay series and symbol for nuclide when
Concept Introduction:
Radioactivity is a nuclear process. It is defined as the spontaneous disintegration of a nucleus which is done by the emission of radiation. The elements which show this property is said to be radioactive elements. Radioactive elements undergo decay by emission of alpha particles and beta particles.
An alpha particle emission causes a decrease of atomic number by 2 and mass number by 4 as the alpha particle is a helium nuclide with two protons and two neutrons whereas emission of beta particle results in an increase of atomic number by 1.
Beta particle is represented as
