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

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,

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

For example,

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.
