Question

Which statements describe nuclear reactions? Check all that apply.

A. Nuclear reactions involve the nuclei of atoms.
B. Nuclear reactions involve the electrons of atoms.
C. The products of nuclear reactions are lighter than the reactants.
D. The products of nuclear reactions are heavier than the reactants.
E. Fission produces energy, while fusion requires energy.

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

Step-by-step 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.
