What is Electron?
An electron is a subatomic particle with a negative elementary charge (−1.602×10⁻¹⁹ C) and a mass approximately 1/1836 that of a proton. Electrons occupy orbitals around the atomic nucleus and are responsible for chemical bonding, electrical conductivity, and most chemical properties. The electron was discovered by J. J. Thomson in 1897.
