Molecules and Extended Structures
Molecules and Extended Structures is a skill on Pengi from Lesson 3: The Atomic Scale in Amplify Science (California) Grade 7.
Key Concepts
Atoms connect in specific ways. Some atoms join in small, individual groups called molecules (like water, H₂O). These are simple structures.
Other atoms connect in massive, repeating 3D grids called extended structures (like salt or metal crystals). Whether simple or complex, these repeating groups define the substance.
