WHAT IS ELECTRON
An electron is a subatomic particle with a negative electric charge that is equal, but opposite to, the positive charge of a proton. These two particles, together with neutrons, form atoms, with the protons and neutrons residing in the nucleus, and the electrons in surrounding orbitals, held in place by the electromagnetic force. They are involved in chemical bonding, can flow through some materials as an electric current, and are responsible for the solidity of solid objects. The particles have a tiny mass, about 1/1836th of the mass of a proton, and are thought to be fundamental, that is, not made up of smaller components.
