Answer:

Proton, neutron, electron

Step-by-step 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
1.6726\cdot 10^(-27) kg, and a positive electric charge of +e (
1.6\cdot 10^(-19)C)

- Neutron: it has a mass of
1.6749 \cdot 10^(-27)kg, 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
9.1094\cdot 10^(-31)kg, and it has a negative electric charge of -e (
-1.6\cdot 10^(-19)C)
