Demonstrate understanding of bonding, structure, properties and energy changes
You need to show that you understand how atoms bond together, why the structure of a substance matters for how it behaves, and the energy released or absorbed when substances change. This standard covers different types of bonding (ionic, covalent, and metallic), what properties those substances have (like hardness or how well they conduct electricity), and how to explain and calculate energy changes in chemical reactions.
You identify key concepts like types of bonding and shapes of molecules, do calculations correctly, and name what type of solid or particle is involved, but don't always explain the connections between ideas.
You link bonding and structure to properties (for example, connecting metallic bonding to malleability), explain molecular shape using VSEPR theory and electronegativity, and round thermodynamic calculations properly with correct units and signs.
You compare and contrast different substances using specific evidence, justify your answers by referencing bonding and structure (for example, explaining why one ionic solid melts at a higher temperature than another), use annotated diagrams, and apply consistent scientific language throughout.
