im doing a question on that right now and the question says:
A neutron is captured by a heavy nucleus. Which type of reaction is this?
The answer is exothermic fission. cuz heavy nucleus (heaving means its fission because its trying to break down to make lighter nuclei). pretty sure exothermic is only for fission and endothermic is only for fusion.

Both are exothermic. A nuclear power plant is an example of using fission to produce energy. Our sun is an example of using fusion to produce energy. Both types of reactions do require some initial energy to start the reaction but after that, both give off huge amounts of energy.

These are not chemical reactions, but are nuclear reactions. Most fusion / fission reactions we hear involve the conversion of some mass into energy--so you can say that these are exothermic.

Fusion would be endothermic because it would use energy to put two or more atoms together. Fission would be exothermic because splitting the atom would create an enormous amount of energy.

Ummm, not exactly.
Both fusion and fission give off heat.
Fission is a violent reaction where all the elements of the atom are exploding outward- Some of them actually are broken into quarks.
Fusion is a much gentler process of combining two elements to become one (with electrons left over).
And those electons give off heat as well. (Albeit, far less than Fission)

All chemical fusion reactions are exothermic and all chemical fission reactions are endothermic.
All fusion reactions release energy and all fission reactions absorb energy.

fusion means two light atoms combine to form a heavy atom and fission means 1 heavy atom split to form lighter atoms.
In both these reactions energy is liberated i.e both these reactions are exothermic.
In both these reactions there is some loss in mass which is converted as energy.It can be found out using Einstein's mass energy relation i.e E=mc^2.

fission reactions are exothermic while fusion reactions are highly endothermic.
