Question

A change in the number of protons or neutrons occurs in which type of reaction?

A: electrochemical reaction

B: thermochemical reaction

C: nuclear reaction

D: chemical reaction

Answer 1

A change in the number of protons or neutrons occurs in which type of reaction? A change in the number of protons or neutrons occurs in nuclear reaction. The answer is letter C. The rest of the choices do not answer the question above.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

When two nuclei and a subatomic particle like proton, neutron or high energy electron collide with each other then it results in the formation of two or more different nuclides.

For example,
`^(6)_(3)Li + ^(2)_(1)H \rightarrow 2^(4)_(2)He`

Whereas in an electrochemical, thermochemical and chemical reaction there occurs change in number of electrons and not in number of protons or neutrons.

Thus, we can conclude that a change in the number of protons or neutrons occurs in nuclear reaction type of reaction.
