Here are the matches between the descriptions in Column A and the types of nuclear decay in Column B:
-
4/2 H - b. Alpha
(This is an alpha particle, which has a mass of 4 and a +2 charge.) -
0/-1 e - c. Beta
(This represents a beta particle, specifically an electron, which has a negative charge.) -
0/0 Y - a. Gamma
(This represents a gamma ray, which is an energy wave with no mass or charge.) -
Has a mass of 4, positively charged: +2 - b. Alpha
(This describes an alpha particle.) -
A negatively charged electron - c. Beta
(This describes a beta particle.) -
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
