Where is so much energy hidden in an atom?

The video turned out a little jerky because a snowstorm started and I underestimated the level of swaying :)...

The atom contains a huge amount of energy and, if you read a physics textbook, it turns out that energy is released both during the decay of the nucleus and during thermonuclear fusion. It’s just that this is written in all the textbooks, but there is not a word about where so much energy comes from in the atom. Where is she hiding? If you break a stick, a characteristic crunch appears. This mechanical wave is formed from a sudden release of energy during a fracture. And in the nucleus of an atom, it seems, subatomic particles are constantly attracted, and how is this energy released? What happens physically during the decay or synthesis of an atomic nucleus? Let's try to answer this question in a simple form and find simple analogies between thermonuclear fusion and nuclear decay. This information is not available anywhere, and the description of the mechanisms of such processes is usually complex and very tricky.
