There are three different subatomic particles in an atom. The nucleus of an atom is composed of protons and neutrons, which are tightly packed together. Orbiting the nucleus, we find the tiny, negatively charged particles known as electrons....
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).

Both nuclear fusion and nuclear fission use the energy stored in atomic particles in the energy production process. An atom consists of a central nucleus and electrons that move around the outside of the nucleus. All elements have proton particles in the nucleus, and electrons, which are much ...
positively- or negatively-charged version of the same atom. A neutrally-charged atom will have the same amount of electrons as protons. Electrons exists in orbitals, which surround the nucleus of the atoms, and it is in these orbitals that electrons can bond with other atoms to form ...
Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
