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

Step-by-step 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.
