2. Binding Energy
 Definition: Binding energy is the energy
required to break a whole system into separate
parts.
 Nuclear Binding Energy:
Nuclear binding energy is the energy that
would be required to disassemble or break the
nucleus of an atom into its component parts.
These components parts are neutrons and
protons. Which are collectively called
“nucleons”.

for
Creating a nucleus.

Breaking up a nucleus.

4. Binding Energy
Now,
 Let mn and mp be the masses of the neutron and
the proton. M = Zmp+ Nmn.
 The mass defect m = Zmp+ Nmn – M(A, Z)
 The energy equivalent to mass defect is,
 E = (m)c2
= (m)×931.49 MeV/u

5. Binding Energy
Here,
 X- Chemical Symbol
 Z- Atomic no. = no. of proton
 A- Mass no.= proton+ neutron
 N- Neutron no.

6. Binding Energy
 The B.E. of the Oxygen:
 B. E= 8mn + 8mp – M
 = (8*1.00866 +8* 1.00782 –15.9994 ) amu
 = (8.0692+8.0625- 15.9994
 = 0.1323*931.49 MeV
 =123.23 MeV

7. BindingBinding Energy Curve

8. Bindin
 This plot shows the amount of binding
energy per nucleon (A nucleon is either a
neutron or a proton. The nucleon number
is the sum of the number of neutrons plus
protons in a nucleus; thus, it is equal to the
atomic mass number)
 This curve indicates how stable atomic
nuclei are; the higher the curve the more
stable the nucleus. Notice the
characteristic shape, with a peak near
A=60. These nuclei are the most stable in
the Universe.
