Atomic Structure and Properties

Atomic structure explores the basic building blocks of matter—atoms. It covers subatomic particles like protons, neutrons, and electrons, and how they arrange in the nucleus and electron cloud.

Understanding atomic properties includes learning about atomic number, mass number, isotopes, and electron configurations. These properties help explain how atoms interact and form bonds with other atoms.

This topic lays the foundation for chemistry because everything else builds on the behavior of atoms and their structure.
