===About Electrons===
: [[Electron]]s have a [[Relative Atomic Charge|relative atomic charge]] of -1 and a [[Relative Atomic Mass|relative atomic mass]] of 1/18601840.
: The [[electron]]s and their [[Electron Orbital|shells]] are responsible for the chemistry of an [[atom]].
: When [[atom]]s [[bond]] to form [[molecule]]s some [[atom]]s can share their [[electron]]s forming a [[Covalent Bond]], some transfer an [[electron]] from one [[atom]] to another forming an [[Ionic Bond]] while others allow [[electron]]s to pass freely between many [[atom]]s forming a [[Metallic Bond]].

===Meaning===
An [[electron]] is a [[Subatomic Particle|subatomic particle]] with a [[Negative Charge|negative charge]] and a very small [[mass]].
===About Electrons===
*'''Electrons''' are fundamental [[particle]]s classified as [[lepton]]s.
*The [[Rest Mass|rest mass]] of an '''electron''' is 9.11×10<sup>−31</sup>kg.
*An '''electron''' has an [[Electrical Charge|electrical charge]] of −1.60×10<sup>−19</sup> [[Coulomb]]s.
*'''Electrons''' participate in [[Chemical Bond|chemical bonding]] and [[electricity]].
*'''Electrons''' can be emitted from a [[metal]] surface through the [[Photoelectric Effect|photoelectric effect]] when exposed to [[Electromagnetic Wave|electromagnetic radiation]] of sufficient [[frequency]].
*'''Electrons''' move around the [[Atomic Nucleus|nucleus]] of an [[atom]] in discrete [[Energy Level|energy levels]] or [[Electron Shell|shells]].
*'''Electrons''' can move between [[Energy Level|energy levels]] in [[atom]]s by absorbing the exact [[energy]] required from an incident [[photon]] or from the [[Kinetic Energy|kinetic energy]] of another '''electron''' [[Collide|colliding]] with it.
*The [antimatter]] counterpart of the '''electron''' is the [[positron]].
