→About Electrical Charge at the Particle Level
: '''Charged''' [[Subatomic Particle|particles]] may exchange virtual [[photon]]s causing a change in their [[momentum]]. This results in the [[force]] of [[attract]]ion or [[repel|repulsion]] between '''charged''' [[Subatomic Particle|particles]].
: As a [[Conservation of Charge|conserved quantity]] '''charge''' cannot be created or destroyed, but it can be transferred from one [[Subatomic Particle|particle]] to another. This occurs in the [[Weak Nuclear Interaction|weak interaction]] via the [[W-boson]].
: The [[Electrical Charge|electrical charge]] passed between [[Subatomic Particle|subatomic particles]] during the [[Weak Nuclear Interaction|weak interaction]] has a [[magnitude]] of 1.60x10<sup>-19</sup> [[Coulomb]]s (the [[Elementary Charge|elementary charge]]).
: The [[Electrical Charge|electrical charge]] of the [[proton]] is +1.60x10<sup>-19</sup> [[Coulomb]]s and the [[Electrical Charge|electrical charge]] of the [[electron]] is -1.60x10<sup>-19</sup> [[Coulomb]]s.
