Quizplus · Accepted Answer

The definition given in the question refers specifically to the concept of radioactive half-life, which is the time required for half of a sample of a radioactive substance to undergo decay and form a new substance. Isotopes are different variations of an element with the same number of protons but different number of neutrons. Radioactivity refers to the property of an atom to emit radiation. Nuclear energy is the energy extracted from atomic nuclei by means of nuclear reactions. None of these options fully captures the concept of radioactive half-life.
