Changes

: The [[electron]], [[W-boson|W^- boson]], [[π-meson|π^- meson]] and [[K-meson|K^- meson]] all carry an [[Electrical Charge|charge]] the same [[magnitude]] as the '''elementary charge''' but with the opposite sign (-1.60x10^-19 [[Coulomb]]s).

: During the [[Weak Nuclear Interaction|weak interaction]] both [[quark]]s and [[lepton]]s can change in [[Electrical Charge|charge]] by a [[magnitude]] of the '''elementary charge'''.
