The '''atomic nucleus''' is the central region of an [[Physics:Quantum atoms/atom|atom]], composed of [[Physics:Quantum particles/proton|protons]] and [[Physics:Quantum particles/neutron|neutrons]]. It contains nearly all of the atom’s mass.

== Description ==
The nucleus is bound together by the strong nuclear force and is much smaller than the overall size of the atom. Electrons occupy regions outside the nucleus in quantum states.

== Properties ==

* nuclear charge
* mass number
* binding energy
