2. Question 1
Unstable nuclei
undergo this process to
become stable.

3. Question 2
It is a kind of decay
where 2 smaller nuclei
come together to form a
more massive nucleus.

4. Question 3
It is a kind of decay
where 1 massive nucleus,
separate when
bombarded by a
neutron.

5. Question 4
It is a kind decay
where the atomic mass
of the daughter nuclei
decreases by 2.

6. Question 5
It is a kind of decay
where the atomic mass
of daughter nuclei
increases by 1.

8. Keep this in
1 atomic mass = 1µ
unit = 931 MeV
mp = 1.0073µ
mn = 1.0087µ

9. Alpha Decay
of Uranium

10. reactant product
Mass Mass product=
reactant= 228.028731 +
232.037146 4.002603=
amu 232.031334 amu

11. Difference between mass of
reactant and mass of products
Mass defect

12. Convert mass defect into energy
Binding Energy

13. Fission of
Uranium

14. reactants products
Mass reactant= Mass product= 137.905 +
235.0439 amu +
94.900 + 3.026= 235.831
1.0087 amu =
236.0526 amu amu

15. Difference between mass of
reactants and mass of products
Mass defect

16. Convert mass defect into energy
Binding Energy

17.  Mass defect- is the difference
between the mass of the product
and reactant when reaction
takes place.
 Binding energy is the mass
defect in terms of energy.

18. Binding Energy: Compared

5.4 MeV MeV

19. “Where does the missing
mass go in a fission
reaction? What is the
application of mass
defect and Binding
Energy?”

20. ASSIGNMENT
