What are subatomic particles

Subatomic particles are the fundamental particles that make up atoms and are smaller in size than atoms. There are three main types of subatomic particles: protons, neutrons, and electrons.

Protons are positively charged particles found within the nucleus (center) of an atom. They have a mass of approximately 1 atomic mass unit (amu).

Neutrons are neutral particles also found within the nucleus of an atom. They have a mass similar to that of a proton, approximately 1 amu.

Electrons are negatively charged particles that orbit the nucleus of an atom in specific energy levels or shells. They are much smaller in mass compared to protons and neutrons, with a mass of approximately 1/2000 amu.

In addition to these three fundamental particles, scientists have discovered other subatomic particles, such as quarks, which are the building blocks of protons and neutrons, and leptons, which include electrons and other particles with similar properties. These particles interact through various fundamental forces, such as electromagnetic, gravitational, weak nuclear, and strong nuclear forces.
