electron
<electronics> A sub-atomic particle with a negative quantised charge. A flow of electrical current consists of the unidirectional (on average) movement of many electrons. The more mobile electrons are in a given material, the greater it electrical conductance (or equivalently, the lower its resistance).

is a negatively charged component of an atom. Element refers to any substance that cannot be separated by chemical means into two or more simpler substances. Endemic means naturally occurring only in a certain region, as in a species that :is endemic to a particular place.

Electrons
One of the elementary particles of nature. They belong to the lepton family and are the negatively charged components of atoms (1.6 x10-19 coulomb). In the simplest model of the atom, electrons are envisaged to move around the atomic nucleus in specified circular and elliptical orbits. When electrons absorb energy from photons, they jump between energy levels which surround the atomic nucleus. This is known as atomic absorption. When the electrons drop back down to their original energy levels, atomic emission takes place during which a photon of electromagnetic radiation is created and emitted (there are no photons in atoms). If a electron absorbs enough energy it will be ejected from the atom altogether. This is a process known as ionisation.

Electron
an elementary particle with a negative electrical charge and a mass 1/1837 that of the proton. Electrons surround the nucleus of an atom because of the attraction between their negative charge and the positive charge of the nucleus. A stable atom will have as many electrons as it has protons. The number of electrons that orbit an atom determine its chemical properties. See also neutron.

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions, its mass is approximately 1/1836 of the proton. Together with atomic nuclei (protons and neutrons), electrons make up atoms. Their interaction with adjacent nuclei is the main cause of chemical bonding.
