When a nucleus is disintegrated, the protons and neutrons that make up the nucleus are released. These protons and neutrons then combine with electrons to form atoms. The atoms that are formed are called the daughter atoms.

The nucleus is the central core of an atom, and it contains the atom's protons and neutrons. The nucleus is very dense, and it contains most of the atom's mass. When a nucleus is disintegrated, a great deal of energy is released. This energy can be used to power nuclear reactors or to create nuclear weapons.
