Electron -

• a particle of matter that has a negative electrical charge and travels around the nucleus of an atom.

• a particle of matter that has a positive electrical charge and forms part of the nucleus of an atom.

• the smallest particle of a substance that can exist. It is composed of one or more atoms.
