Question
Chapter 18.6, Problem 18.6P
Interpretation Introduction
Interpretation:
Mass of atomic nucleus is less than sum of masses of protons and neutrons present in nucleus of atom has to be explained.
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.
Binding energy represents energy that would be released when protons and neutrons combined to form nucleus.
