Inphysics,acharged particleis aparticlewith anelectric charge.For example, someelementary particles,like theelectronorquarksare charged.[1]Some composite particles likeprotonsare charged particles. Anion,such as amoleculeoratomwith a surplus or deficit ofelectronsrelative toprotonsare also charged particles.
Aplasmais a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles.
Charged particles are labeled as eitherpositive(+) ornegative(-). The designations are arbitrary. Nothing is inherent to a positively charged particle that makes it "positive", and the same goes for negatively charged particles.
Examples[edit]
Positively charged particles[edit]
- protons
- positrons(antielectrons)
- Alpha particles
- positivecharged ions
- cations
Negatively charged particles[edit]
- electrons
- antiprotons
- muons
- tauons
- negativecharged pions
- anions
Particles with zero charge[edit]

- Charge carrier– refers to moving charged particles that create anelectric current
