Atomic Structure and Models for Explaining Properties of Elements and Ions

Introduction to Matter and Elements → Assessment: Explain Properties Using Atomic Models

This path introduces high school students to the fundamental concepts of atomic structure, including subatomic particles, atomic number, mass number, isotopes, and ions. It progresses through historical atomic models to modern electron shell theory, enabling learners to use these models to explain periodic properties and ion formation. The path emphasizes hands-on practice and assessment to solidify understanding.
