Electron

The smallest of the three particles which make up atoms and the one which carries the negative charge.

Electric current consists of the flow of electrons through a conductor. It follows that electrical conductors have their electrons loosely tied to the atoms – a characteristic of metals, whereas non-conductors, or insulators, have their electrons tightly bound to the atoms.
