What are the three subatomic particles that make up an atom

Physics
1 answer:
Harrizon [31]3 years ago
5 0

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 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)

Why are you unable to observe the wavelike motion of a soccer ball as it is kicked toward a goal?
aalyn [17]
We all know that a soccer ball is composed of matter, and matter is made up of particles of atoms such as protons and electrons, and matter of  soccer ball can also be made up of waves of electrons and protons. This is now in a realm of quantum mechanics were everything defies our logic and common sense. Atoms can be defined as particle and also as a wave, they called it particle wave duality, it means atoms behave as wave and a particle. This is the trickiest part, Imagine that you are not observing the flight of the soccer ball, it actually behave as a wave as it moves in its trajectory, but at the moment that you are going to observe the flight of the soccer ball, it will behave as a particle as you see on its trajectory, becoming a ball or a particle, and that is the weird of part of quantum mechanics, the world of subatomic particles defies all common sense or logic. Remember that we will never see the wave like motion of any particle, because nature always plays a trick on our mind or senses.
