Question # 1

Define mass defect and binding energy.

  • Ans 1: Mass defect: The mass of the nucleus is always less than the total mass of the protons and neutrons that make up the nucleus,The difference of the two masses is called mass defect.
    Binding energy:The missing mass is converted into energy at the formation of the nucleus and is called binding energy.
