Question

In a nuclear reaction, energy is released by the combination of two elements into a new element. This process is an example of

Answer 1

The process is nuclear fusion

Answer 2

Explanation:

A nuclear fusion is defined as the reaction in which two small nuclei combine together and result in the formation of a large nuclei.

For example, $^{2}_{1}H + ^{2}_{1}H \rightarrow ^{4}_{2}He$

Whereas a reaction in which a large nuclei divides into two small nuclei is known as a nuclear fission reaction.

For example, $^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He$

Thus, we can conclude that in a nuclear reaction, energy is released by the combination of two elements into a new element. This process is an example of nuclear fusion.
