Key Stage 5
Meaning
The elementary charge (e) is the charge of a proton, +1.60x10-19.
About The Elementary Charge
- The W+ boson, π+ meson and K+ meson all carry the elementary charge (+1.60x10-19).
- 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).
- During the weak interaction both quarks and leptons can change in charge by a magnitude of the elementary charge.
| Particle | Charge/e |
| Proton (\(p\)) | \(+1\) |

| Muon (\(\mu\)) | \(-1\) |
| π+ meson (\(\pi^+\)) | \(+1\) |
| π- meson (\(\pi^-\)) | \(-1\) |
| K+ meson (\(K^+\)) | \(+1\) |
| K- meson (\(K^-\)) | \(-1\) |
