# Learning Objectives Unit 2 - Particles with Internal Structure ## Content Objectives **LO1: Electrostatic charge** * Recognize that the need for an evolved atomic model arose from the observed interactions between charged objects. * Connect historical experimental evidence features of Thomson's Plum Pudding model. * Apply the Plum Pudding model to explain interactions between charged objects. **LO2: Distinguishing between substances** * Utilize differences in electrical conductivity to distinguish between: * Metals * Nonmetals * Types of compounds (ionic vs. molecular/covalent) * Charged particles, electrons, ions, atoms **LO3: Particle Arrangement** * Use models of particle arrangement from x-ray crystallography to distinguish between types of substances. * Atoms * Molecules * Elements * Compounds (ionic and molecular/covalent) **LO4: Particle Arrangement and Properties** * Make connections between particle arrangement and properties of a substance * Melting point * Boiling point * State of matter at room temperature * Conductivity **LO5: Determining Charge** * Determine the type and quantity of charge carried by particles based on experimental evidence. **LO6: Nomenclature for Simple Inorganic Compounds** * Apply a differentiated system of nomenclature for simple inorganic compounds * Binary ionic compounds * Binary ionic compounds containing transition metals * Molecular (covalent) compounds * Ionic compounds containing polyatomic ions **LO7: Representing Particles** * Represent atoms, ions, and molecules using particle diagrams.
