Question

What is one way in which fission differs from fusion?

A) Fission splits nuclei, fusion combines nuclei.
B) Fission releases energy, fusion absorbs energy.
C) Fission is not a radioactive process, fusion is radioactive.
D) Fission deals with the nucleus, fusion pertains to the electrons.

Answer 1

A) Fission splits nuclei, fusion combines nuclei.

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step 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.
