Question

Draw a curve between mass number and average binding energy per nucleon.

Answer 1

Answer:

· A heavy nucleus X of mass number 240 and binding energy per nucleon 7.6 MeV is split into two fragments Y and Z of mass numbers 110 and 130. The binding energy of nucleons in Y and Z is 8.5 MeV per nucleon. Calculate the energy Q released per fission in MeV.

Answer 2

Binding energy of nucleon is the energy require to break the bond of nucleon from its atom

Explanation:

• In the given curve we see different amount of energy is required for different atoms peaks in the given curve shows that the energy of these specified atoms is more as compare to the neighboring atoms
• Binding energy per nucleon is the amount of energy required to disintegrate the nucleon from any given atom
• In the given curve Fe (iron 56) have more energy and it is most stable atom among all
• Left side curve shows that atoms are less stable as atoms are small in size so these can be attached to another atoms to make them stable and shows nuclear fusion property
• Similarly right side of the curve shows that atoms are again less stable as have large size so can disintegrate easily to make them stable so shows nuclear fission properties
• Curve is in attachment below
