Question

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

Column A
1. 4/2 H

2. 0/-1 e

3. 0/0 Y
4. Has a mass of 4, positively charged: +2:
5. A negatively charged electron:
6. An energy wave:
Column B
a. Gamma
b. Alpha
c. Beta

Answer 1

Here are the matches between the descriptions in Column A and the types of nuclear decay in Column B:

1. 4/2 H - **b. Alpha**
(This is an alpha particle, which has a mass of 4 and a +2 charge.)

2. 0/-1 e - **c. Beta**
(This represents a beta particle, specifically an electron, which has a negative charge.)

3. 0/0 Y - **a. Gamma**
(This represents a gamma ray, which is an energy wave with no mass or charge.)

4. Has a mass of 4, positively charged: +2 - **b. Alpha**
(This describes an alpha particle.)

5. A negatively charged electron - **c. Beta**
(This describes a beta particle.)

6. An energy wave - **a. Gamma**
(This describes gamma radiation.)

So, the final matches are:
1 - b
2 - c
3 - a
4 - b
5 - c
6 - a
