# Learning Objectives Unit 2 - Particles with Internal Structure **Unit 2 - Particles** **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 to features of Thomson's Plum Pudding model. * Apply the Plum Pudding model to explain interactions between charged objects. **LO2: Distinguishing 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: Charge Determination** * Determine the type and quantity of charge carried by particles based on experimental evidence. **LO6: Inorganic Compound Nomenclature** * 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: Particle Diagrams** * Represent atoms, ions, and molecules using particle diagrams.
