How is fusion different from fission?

Response: Nuclear fusion is the process by which nuclei from more than one atom join together. A heavier nucleus is formed in the process.

Depending on the nuclei involved, it may result in either the release or absorption of energy. Generally speaking, when nuclei lighter than iron and nickel fuse, energy is released. On the other hand, when nuclei heavier than these nuclei join, energy is absorbed.

Of course, the reverse process, i.e. the disintegration of a ...
