Question

What is one way in which fission differs from fusion?

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

Nuclear fission is a process in which a heavy radioactive nucleus splits into two or more smaller nuclei.

For example, $^{235}_{92}U + ^{1}_{0}n \rightarrow ^{236}_{92}U\rightarrow ^{92}_{36}Kr + ^{141}_{56}Ba + 3^{1}_{0}n$ is a nuclear fission reaction.

Whereas in a nuclear fusion reaction two small nuclei combine together to result in the formation of a heavy nuclei.

For example, $^{2}_{1}H + ^{3}_{1}H \rightarrow ^{4}_{2}He + ^{1}_{0}n + Energy$

Thus, we can conclude that one way in which fission differs from fusion is that fission splits nuclei, fusion combines nuclei.  

Answer 2

A) Fission splits nuclei, fusion combines nuclei.
