What is the source of energy in fission and fusion?

Answer 1

Nuclear fission is the breaking down of an atom's nucleus. This happens because of the small range of activity of the strong interaction, the force that holds the nucleus together. When a atom's nucleus exceeds the size/range the strong interaction can hold, the whole nucleus will breakdown, releasing large amounts of energy. The protons and neutron will scatter go into other nuclei (plural), breaking the other nuclei down, causing chain reactions and releasing more energy. This energy is used to boil water like burning coal in conventional power plants.

Nuclear fusion cannot occur on Earth. It only occurs in the sun and other stars.

Answer 2

It is the strong and weak nuclear force that binds the protons and nutrons together in the nucleus of an atom. When these bonds break to create new atoms (fission) or form to create new atoms (fusion), they release a lot of energy.

Answer 3

Fission:

One heavy atomic nucleus splits into two or more separate lighter atomic nuclei.

The masses of all the pieces add up to less than the mass of the first one.

Fusion:

Two light atomic nuclei join up and form a single heavier atomic nucleus. The mass

of the combination is less than the sum of the masses of the original two.

In both cases, the missing mass leaves the site of the conversion in the form of energy.

Answer 4

It is essentially the internal binding energy of the nuclei involved, which is a function of the forces between the nucleons and the way the aggregate of these forces varies with the size of nuclei.

Answer 5

In fission, the source of energy comes from splitting heavy atomic nuclei into lighter ones, releasing a large amount of energy in the process. In fusion, energy is released when light atomic nuclei combine to form a heavier nucleus, typically in the core of stars like the Sun.
