Atomic structure

An atom consists of a small, dense nucleus composed of nucleons (i.e. protons and neutrons), surrounded by a diffuse "cloud" consisting of one or more electrons.

The nucleons are held together by the strong force. The electrons are attracted to the nucleus and interact with it via the electromagnetic force.
