MASS DEFECT Meaning and
Definition
-
Mass defect refers to the difference in mass between a nucleus and the sum of its individual nucleons (protons and neutrons) when they are measured separately. It arises due to the phenomenon of mass-energy equivalence, as described by Einstein's famous equation, E=mc².
In nuclear physics, the mass defect is a key concept to understand the release of nuclear energy. The mass of a nucleus is determined by the total mass of its constituent protons and neutrons. However, the measured mass of a nucleus is found to be slightly less than the sum of its nucleons' individual masses. This discrepancy in mass is referred to as the mass defect.
The mass defect arises from the conversion of some of the nucleonic mass into binding energy. According to Einstein's equation, this mass is converted into energy, which is binding the nucleons together within the nucleus. The binding energy is responsible for the stability and integrity of the nucleus.
The concept of mass defect is closely related to nuclear binding energy. The higher the binding energy, the stronger the nuclear force, and the more stable the nucleus. The release of this binding energy, either in the form of nuclear fission or fusion, is harnessed in nuclear power plants or nuclear bombs, generating tremendous amounts of energy.
The mass defect is quantified by calculating the difference between the actual mass of a nucleus and the sum of its constituent nucleons, typically expressed in atomic mass units (amu) or electron volts (eV). The mass defect plays a crucial role in understanding nuclear reactions, as it determines the amount of energy released or absorbed during such processes.

Etymology of MASS DEFECT
The word "mass defect" is derived from two different terms: "mass" and "defect".
1. "Mass": The term "mass" comes from the Latin word "massa", which means a "lump" or "mass". It entered the English language through Old English and has been in use since the 14th century. In physics, "mass" is a fundamental property of matter that determines its inertia and gravitational attraction.
2. "Defect": The word "defect" comes from the Latin word "defectus", which means "failure" or "imperfection". It also entered the English language through Old English and has been used since the 15th century. In general, a "defect" refers to an imperfection or lack in something.
