The electron is a subatomic particle that carries a negative electric charge. It has no known substructure and is believed to be a point particle.[2]. read more

Atomic theory describes electrons as surrounding the proton/neutron nucleus of an atom in shells. While it's theoretically possible for an electron to be found anywhere in an atom, it is most probably to find one in its shell. An electron has a spin or intrinsic angular momentum of 1/2. read more

Electrons radiate or absorb energy in the form of photons when they are accelerated. Laboratory instruments are capable of trapping individual electrons as well as electron plasma by the use of electromagnetic fields. Special telescopes can detect electron plasma in outer space. read more
