Lesson: Elements, Atoms, and Molecules Chemistry • 7th Grade

Students will be able to

• define elements, atoms, and molecules,
• analyze different drawn representations of chemical species in order to classify diagrams of elements, atoms, and molecules,
• compare intermolecular forces to intramolecular bonds to understand why changes in state do not always decompose the chemical,
• identify and label different chemical species as solids, liquids, and gases using the appropriate state symbols to better explain the species in chemical equations.
