📝 Mass Defect
〽️The actual mass of the atomic nucleus is always less than the mass of protons and neutrons present in the nucleus. When a nucleus is formed, energy is released. This energy is removed in the form of a reduction in total mass. This missing mass is known as the ‘mass defect’ and it accounts for the energy released.
〽️The mass defect (𝚫M) can be calculated by subtracting the original atomic mass (MA) from the sum of the mass of protons (mp= 1.00728 amu) and neutrons (mn= 1.00867 amu) present in the nucleus.
〽️Mass defect formula:
𝚫M = (Zmp + Nmn) – MA
𝚫M – mass defect
MA – mass of the nucleus
mp – mass of a proton, i.e. 1.00728 amu
mn – mass of a neutron, i.e. 1.00867 amu
Z – number of protons
N – number of neutrons
