What is the mass defect? and binding energy in MeV for atom?

The atomic mass of Helium-3 (3/2He) is 3.014694 amu. Calculate the:
a) mass defect for this atom?
b) binding energy in MeV for this atom?

Answer 1

Actually the sum of mass of individual ( say ( 2 proton and 2 neutron) nucleons is slightly greater than mass of atom made of those nucleons ( 2He4)
is different. Some amount of mass is used to bind those nucleons.
The difference in mass is known as mass defect.

Mass of Proton is 1.0072764 amu Mass of Neutron 1.0086649 amu So, mass of (2 proton and 1 neutron) is 3.023216 amu and mass of He(3,2) is given 3.014694 amu Mass difference #deltam=0.008522 # amu Using 1 amu =931 mev binding energy is #(0.008522*931)=7.933 Mev#

Answer 2

The mass defect refers to the difference between the mass of an atomic nucleus and the sum of the masses of its constituent protons and neutrons. Binding energy, on the other hand, is the energy required to disassemble a nucleus into its constituent protons and neutrons. The relationship between mass defect and binding energy is described by Einstein's famous equation, ( E=mc^2 ), where ( E ) is energy, ( m ) is mass, and ( c ) is the speed of light. The mass defect of a nucleus is directly related to its binding energy through this equation.

In terms of units, binding energy is often expressed in electron volts (eV) or mega-electron volts (MeV), where 1 MeV is equal to ( 1 \times 10^6 ) eV. When calculating the binding energy of an atom in MeV, the mass defect is typically converted from atomic mass units (u) to kilograms, and then multiplied by ( c^2 ) to obtain the energy in joules. Finally, the energy in joules can be converted to MeV by dividing by ( 1.602 \times 10^{-13} ) (the conversion factor from joules to MeV).

Answer 3

The mass defect refers to the difference in mass between a nucleus and the sum of its constituent nucleons (protons and neutrons). Binding energy, often expressed in MeV (megaelectronvolts), is the energy required to separate a nucleus into its constituent nucleons. It is related to the mass defect through Einstein's mass-energy equivalence equation (E=mc^2), where the mass defect is converted into binding energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
