The statement which is always true when nuclear fusion occurs is "the combined number of protons and neutrons remains constant".

What is nuclear fusion?

Nuclear fusion is a type of reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

The equation 21H+ 21H→ 42H+energy represent that there are two atoms with mass numbers of 2.

The true statement during a fission chain reaction is "the number of freely-moving neutrons increases over time".

Fission chain reaction is a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats.
