What is Electron

An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton. Electrons surround the positively charged protons in the nucleus of an atom and the number of electrons determine the atomic element. Elements that loose electrons easily make good conductors and elements whose electrons are tightly bound together make good insulators. It is this movement of electrons which is the electric current in circuits.
