_{1} ^{2} Y

_{2} ^{3} Z

_{0} ^{1} n

+ energy

fusion reaction
fission reaction
Chain reaction
radioactive decay

Solution:

Concept:

Light nuclei combine to form a heavier nucleus, releasing energy.

Explanation:

Two light nuclei,

_{1}^{2}X

and

_{1}^{2}Y

, fuse to form a heavier nucleus

_{2}^{3}Z

and a neutron

_{0}^{1}n

.

This process of combining small nuclei to form a larger nucleus is called nuclear fusion.
