Ideally the strong nuclear force would say how the protons and neutrons are bonded together, but there is a conceptual chasm in this area. It is unclear how the residual nuclear force (at nucleus level) emerges from the strong force (at quark level), except as a general concept that the gluons leak out.
Nuclear energy can be used to create electricity, but it must first be released from the atom. Encyclopedic entry. Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atoms dense nucleus. In fact, the power that holds the nucleus together is officially called the strong force.
