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.
