The fraction of a radioisotope that left after the passage of seven half-lives is to be stated. Concept introduction: The elements whose nucleus decays spontaneously are known as radioactive elements. The decay is accompanied by the emission of alpha particles, beta particles, and gamma rays. All the elements which have an atomic number greater than 83 are radioactive. Half-life of a radioactive substance is defined as the time taken by half of its atoms to decay.
