Big Idea 2: Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions, or molecules and the forces between them.
Enduring Understandings
Enduring understanding 2.A: Matter can be described by its physical properties. The physical properties of a substance generally depend on the spacing between the particles (atoms, molecules, ions) that make up the substance and the forces of attraction among them.
Enduring understanding 2.C: The strong electrostatic forces of attraction holding atoms together in a unit are called chemical bonds.
Enduring understanding 2.D: The type of bonding in the solid state can be deduced from the properties of the solid state.
Learning Objectives
LO 2.1 Students can predict properties of substances based on their chemical formulas, and provide explanations of their properties based on particle views. [See SP 6.4, 7.1]
LO 2.22 The student is able to design or evaluate a plan to collect and/or interpret data needed to deduce the type of bonding in a sample of a solid. [See SP 4.2]
LO 2.23, 2.27, 2.29, 2.31 The student can create a representation of an ionic solid/metallic solid/covalent solid/molecular solid that shows essential characteristics of the structure and interactions present in the substance. [See SP 1.1]
LO 2.24, 2.28, 2.30, 2.32 The student is able to explain a representation that connects properties of an ionic solid/metallic solid/covalent solid/molecular solid to its structural attributes and to the interactions present at the atomic level. [See SP 1.1, 6.2, 7.1]
