Many scientists determined this through series of tests after its invention.
A change from one form of matter to another, with the release of large amounts of energy.
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
This took a lot of effort by various research establishments, notably Oak Ridge and Los Alamos during WW2, and after that by others including Harwell in the UK.
The energy in a nuclear reaction comes from the release of some of the residual binding energy that holds the nucleus together. When you split heavy isotopes, such as uranium-235, or when you fuse light isotopes, such as hydrogen-2, the total binding energy required is reduced by a small amount. This difference is released as heat and radiation.
The release of excess binding energy.

Nuclear fusion. Hydrogen atoms combine to become helium, and as a product if that reaction a tiny amount of energy is released as an explosion.
Due nuclear reaction on sun which are uncontrolled chain reaction with huge amount of energy
If you consider the equation, E=mc2, you can see that an amount of mass can be considered as equal to an amount of energy. In other words, we could take all the mass in a nuclear reaction and figure out how much energy that represents. If you add that to the amount of energy present at the same time, you get a summation of energy (some of which is mass represented as energy). That amount of energy does not change in a nuclear reaction.
