Electron charge (e) is a fundamental physical constant stating the naturally occurring unit of electric charge. The initial idea behind the measurement of electron's charge was put forth by Robert Millikan in his oil-drop experiment in 1909. It is a negative elementary electric charge equal to 1.6021765 × 10-19 coulomb and represented by the symbol e− or β−. Electron's charge is 1 when the elementary charge is expressed in atomic units.
