Question

Which statements describe nuclear reactions? Check all that apply.

Answer 1

The answer is A Nuclear reactions involve the nuclei of atoms & C The products of nuclear reactions are lighter than the reactants.

Answer 2

Explanation:

Nuclear reactions are the reactions in which nucleus of an atom changes either by splitting or joining with the nucleus of another atom.

There are two types of nuclear reactions.

• Nuclear fission - In this process, large atomic nuclei splits into smaller nuclei.  
• Nuclear fusion - In this process, two small nuclei combine together to form a large nuclei.

Both nuclear fission and fusion processes involve nuclei of atoms.

For example, $^{0}n + ^{235}_{92}U \rightarrow ^{236}_{92}U \rightarrow ^{144}_{56}Ba + ^{89}_{36}Kr + 3n + 177 MeV$

Thus, we can conclude that statements which are true are as follows.

• Nuclear reactions involve the nuclei of atoms.  

• The products of nuclear reactions are lighter than the reactants.
