Subatomic Particles

Subatomic particles are the particles that make up an atom. There are three main subatomic particles: protons, neutrons, and electrons. These particles are the building blocks of matter and play a crucial role in the structure and behavior of atoms.

Protons

Protons are positively charged particles found in the nucleus of an atom. They have a relative mass of 1 and a charge of +1.

Neutrons

Neutrons are neutral particles found in the nucleus of an atom. They have a relative mass of 1 and no charge (neutral).

Electrons

Electrons are negatively charged particles that orbit the nucleus of an atom in specific energy levels or shells. They have a relative mass of nearly 0 and a charge of -1.
