Question

What parts of an atom can change during a nuclear reaction that cannot change during a chemical reaction? Question 15 options: A. The number of protons and neutrons B. The number of electrons only C. The number of protons and electrons D. The number of neutrons and electrons

Answer 1

Answer;

B. the number of protons and neutrons

Explanation;

• Nuclear reactions involve a change in the nucleus of an atom, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
• Therefore the parts of an atom that can change during a nuclear reaction but can not change during a chemical reaction is the number of protons and neutrons that are found in the nucleus.

Answer 2

Neutrons and protons cannot be removed from nucleus from chemical reactions because they are strongly held together but nuclear reactions are strong enough to separate them. Hence option A is correct.
