Charged particle
In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can also be an electron or a proton, or another elementary particle, which are all believed to have the same charge[1] (except antimatter). Another charged particle may be an atomic nucleus devoid of electrons, such as an alpha particle.
A plasma is a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles.
Examples
Positively charged particles
- protons and atomic nuclei
- positrons (antielectrons)
- alpha particles
- positive charged pions
- cations
Negatively charged particles
- electrons
- antiprotons
- muons
- tauons
- negative charged pions
- anions
Particles without an electric charge
gollark: That is probably it.
gollark: Go to the shell, type `lua`, press enter, type `turtle.digDown()`, press enter.
gollark: If you use the actual lua prompt it'll show you the return values.
gollark: What happens if you open `lua` and run `turtle.digDown()` in the prompt?
gollark: This is probably obvious but your turtle has a pickaxe equipped, right?
