When we measure the nuclear masses and compare them with the masses of the constituent nucleus in free states, the mass of the nucleus is always less than the mass of the constituent nucleons. The difference in mass is known as:
Correct answer: A. Mass Defect
- A. Mass Defect
- B. Mass Value
- C. Mass Disorder
- D. Mass Energy
- E. Mass Nucleus
Explanation
Mass defect: When we measure the nuclear masses and compare them with the masses of constituent nucleus in free states, the mass of the nucleus is always less than the mas of constituent nucleons. The difference in mass is known as mass defect. Mass value: Mass (symbolized m) is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg). Mass disorder: MASS syndrome is a medical disorder of the connective tissue similar to Marfan syndrome. Mass energy: The equation developed by Albert Einstein, which is usually given as E = mc², showing that, when the energy of a body changes by an amount E (no matter what form the energy takes), the mass (m) of the body will change by an amount equal to E/c². Mass Nucleus: The mass of the nucleus is associated with the atomic mass number, which is the total number of protons and neutrons in the nucleus of an atom.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
