Answer:
Proton, neutron, electron
Explanation:
The atom consists of a nucleus, where almost all the mass is concentrated, and electrons orbiting around the nucleus.
The nucleus consists of two types of particles:
- Proton: it has a mass of [tex]1.6726\cdot 10^{-27} kg[/tex], and a positive electric charge of +e ([tex]1.6\cdot 10^{-19}C[/tex])
- Neutron: it has a mass of [tex]1.6749 \cdot 10^{-27}kg[/tex], and it has no electric charge
The third particle that makes an atom is the electron, that orbit around the nucleus:
- Electron: it has a mass of [tex]9.1094\cdot 10^{-31}kg[/tex], and it has a negative electric charge of -e ([tex]-1.6\cdot 10^{-19}C[/tex])
