The electron is a fundamental subatomic particle that carries a negative electric charge. See also electron [1]

In industry

Electron beams are used in welding as well as lithography.

Usage

Electron microscopes are used to magnify details up to 500,000 times. Quantum effects of electrons are used in Scanning tunneling microscope to study features at the atomic scale.
