Answer 1

To match the descriptions of nuclear decay to the type of nuclear decay, you can align the items in Column A with their corresponding types of decay.

Here's the match:

1. **4/2 He**:
- **Type of decay**: Alpha decay
- **Description**: Has a mass of 4, positively charged: +2

2. **0/-1 e**:
- **Type of decay**: Beta decay
- **Description**: A negatively charged electron

3. **0/0 Y**:
- **Type of decay**: Gamma decay
- **Description**: An energy wave

So, the completed matching will be:

1. 4/2 He → Alpha decay
2. 0/-1 e → Beta decay
3. 0/0 Y → Gamma decay
