It's Very Useful To Study Radioactive Decay

2. What Is Radioactivity?
• The emission of elementary particles by some
atoms when their unstable nuclei disintegrate
(see half-life). Materials composed of such
atoms are radioactive. (See alpha radiation,
beta radiation, and gamma radiation.)
• the emission of ionizing radiation or particles
caused by the spontaneous disintegration of
atomic nuclei.Is Called Radioactivity

8. Mass Defect
• The actual mass is always less than the sum of
the individual masses of the constituent
protons and neutrons because energy is
removed when the nucleus is formed. This
energy has mass, which is removed from the
total mass of the original particles. This mass,
known as the mass defect,

9. Binding Energy
• Nuclear binding energy is
the minimum energy that would be required to
disassemble the nucleus of an atom into its
component parts. These component parts
are neutrons and protons, which are collectively
called nucleons. The binding energy is always a
positive number, as we need to spend energy in
moving these nucleons, attracted to each other
by the strong nuclear force, away from each
other.
