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 (\(p\))	\(+1\)
Electron (\(e\))	\(-1\)
Muon (\(\mu\))	\(-1\)
π⁺ meson (\(\pi^+\))	\(+1\)
π^- meson (\(\pi^-\))	\(-1\)
K⁺ meson (\(K^+\))	\(+1\)
K^- meson (\(K^-\))	\(-1\)
Up-quark (\(o\))	\(+\frac{2}{3}\)
Down-quark (\(d\))	\(-\frac{1}{3}\)
Strange-quark (\(s\))	\(-\frac{1}{3}\)
Top-quark (\(t\))	\(+\frac{2}{3}\)
Bottom-quark (\(b\))	\(-\frac{1}{3}\)
Charm-quark (\(c\))	\(+\frac{2}{3}\)
