Subatomic Particles

Subatomic particles are the particles that make up atoms. These particles include protons, neutrons, and electrons. They are the building blocks of matter and play a crucial role in the structure and behavior of atoms.

Protons

Protons are positively charged subatomic particles found in the nucleus of an atom. They have a relative mass of 1 and are crucial for determining the atomic number of an element.

Neutrons

Neutrons are neutral subatomic particles found in the nucleus of an atom. They have a relative mass of 1 and contribute to the stability of the nucleus through the strong nuclear force.

Electrons

Electrons are negatively charged subatomic particles found in the electron cloud surrounding the nucleus of an atom. They have a much smaller mass compared to protons and neutrons and are involved in chemical bonding and electricity.
