Electron

Subatomic particle that is small in size, capable of substantial movement relative to the atomic nucleus, and negatively charged.

Electrons vary in the amount of energy that is associated with them. Generally the further that an electron lies from an atomic nucleus then the more energy that is associated with it, just as the higher water is against a dam the more power that is associated with that water.

This distance can be increased, for example, when an electron absorbs the energy associated with a photon. The "height" of an electron away from an atomic nucleus can be "locked" into place within chemical bonds.

Note that the small size of electrons is as in comparison with protons.

The following video covers electron atomic orbitals, absorption spectra, and emission spectra:
