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
, and a positive electric charge of +e (
)
- Neutron: it has a mass of
, 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
, and it has a negative electric charge of -e (
)
Newton’s Second Law concerns the generation of force based on an object’s mass and acceleration, as described by the equation F=ma.
Hope this helps!
