Question 12
Match the description of nuclear decay to the type of nuclear decay.

Column A
1.
4/2 He
2.
0/-1 e
3.
0/0Y




4.
Can be stopped by paper:
Can be stopped by paper
5.
Can be stopped by aluminum:
Can be stopped by aluminum
6.
Can be stopped by lead:
Can be stopped by lead
Column B
a.Gamma
b.Beta
c.Alpha

Answer 1

To match the description of nuclear decay to the type of nuclear decay, here is the correct pairing:

Column A
1. 4/2 He - **c. Alpha**
2. 0/-1 e - **b. Beta**
3. 0/0 Y - **a. Gamma**

Column A (Descriptions of stopping power):
4. Can be stopped by paper: - **c. Alpha** (Alpha particles can be stopped by a sheet of paper.)
5. Can be stopped by aluminum: - **b. Beta** (Beta particles can be stopped by aluminum.)
6. Can be stopped by lead: - **a. Gamma** (Gamma rays require lead or other dense materials for significant attenuation.)

So the final pairs are as follows:

1. c. Alpha
2. b. Beta
3. a. Gamma
4. c. Alpha
5. b. Beta
6. a. Gamma
