This post will focus in finding mass defect and binding energy of a reaction. In the last post, I did not mention about binding energy. Here, we will learn how to calculate binding energy as well. Lets find mass defect and binding energy for following equation:
Mass of Ne-21= 20.99 u Mass of He-4 = 4.002 u Mass of Mg-24 = 23.98 and Mass of n= 1.008
Then, Mass defect = (mass of Ne + Mass of He) - (Mass of Mg + Mass of n)
= (20.99 u + 4.002 u) - (23.98 u + 1.008 u)
= 24.992 u - 24.988 u
= 0.004 u
There are two unit to calculate binding energy one in MeV and second one is in J. In this we will calculate in MeV because it is the SI unit for binding energy and fastest plus easiest way to calculate.
Binding Energy = Mass defect × 931.49 MeV/u
= 0.004 u × 931.49 MeV/u
= 3.726 MeV
as result of nuclear decay process, either fusion or fusion reaction or formation of nuclear force
ReplyDeletethe mass defect is as result of formation of binding energy in in stables atoms, the mass defect is equal to the amount of mass converted to energy needed to hold the nucleons together in the nucleus of atoms.
the mass defects can be defined as the mass lost when an aggregate amount of protons and neutrons come together to form a nucleus.
