The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.

This source of energy can be produced in two ways:

fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together.

Explanation

Explanation

Thermal energy is produced during fission reactions in nuclear reactors, which is used to generate electricity.

Explanation

Atomic nuclei consist of electrically positive protons and electrically neutral neutrons.

The nucleus makes up much less than. 01% of the volume of the atom,

but typically contains more than 99.9% of the mass of the atom.
