Key Stage 5
Meaning
The elementary charge (e) is the charge of a proton, +1.60x10-19 Coulombs.
About The Elementary Charge
- The W+ boson, π+ meson and K+ meson all carry the elementary charge (+1.60x10-19 Coulombs).
- The electron, W- boson, π- meson and K- meson all carry an charge the same magnitude as the elementary charge but with the opposite sign (-1.60x10-19 Coulombs).
- During the weak interaction both quarks and leptons can change in charge by a magnitude of the elementary charge.
