Understand that an atom is composed of smaller particles called subatomic particles, which determine its structure and properties.
Recall the three major subatomic particles that make up an atom: protons, neutrons, and electrons.
Recognize that protons carry a positive charge and are found in the nucleus of the atom.
Know that neutrons have no charge (are neutral) and are also located in the nucleus alongside protons.
Remember that electrons carry a negative charge and orbit the nucleus in electron clouds or shells.
