4/2 He

2.


0/-1 e

:


3.


0/0 Y
:


4.
__Has a mass of 4, positively charged: +2:
__Has a mass of 4, positively charged: +2
5.
A negatively charged electron:
A negatively charged electron
6.
An energy wave:
An energy wave

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
