Answer:
Proton - Location: nucleus, charge: +e
Neutron - Location: nucleus, charge: 0
Electron - Location: orbiting the nucleus, charge: -e
Explanation:
An atom consists of three particles:
- Proton, which is a positively charged particle, with charge +e (where is the fundamental charge), located in the nucleus
- Neutron, which is a neutral particle with approximately same mass of the proton, but zero electric charge
- Electron, which is a negatively charged particle, with opposite charge to the proton (-e), but with much smaller mass than the proton (the mass of the electron is approximately 1800 times smaller than the mass of the proton). The electron is not located in the nucleus of the atom, but instead it orbits around it.
