What is the difference between an electron and a proton

An electron is a sub-atomic particle and has a negative charge and a proton is another sub-atomic particle and has a positive charge. Neurons are neutral sub-atomic particles with no charge.

Electric charge: the proton and electron are electrically charged, while the neutron is not. The proton and electron, however, are oppositely charged. Role in the atom: Protons and neutrons are closely bound together in the nucleus of an atom, while electrons are spread out around the nucleus.
