Study Notes
Learning Objectives for Unit 2: Particles with Internal Structure
- LO1: Electrostatic charge is a new property, recognize need for an evolved atomic model based on observed interactions between charged objects, relate historical experimental evidence to the features of Thomson's Plum Pudding model, apply the Plum Pudding model to interactions between charged objects.
Distinguishing Substances
- LO2: Utilize electrical conductivity to distinguish between metals, nonmetals, types of compounds (ionic vs molecular/covalent), charged particles (electrons, ions, atoms).
Particle Arrangement and Properties
-
LO3: Use models of particle arrangement from x-ray crystallography to distinguish between types of substances (atoms, molecules, elements, compounds).
-
LO4: Connect particle arrangement to substance properties: melting point, boiling point, state of matter, conductivity.
Charge and Nomenclature
-
LO5: Determine the type and quantity of charge carried by particles, based on experimental evidence.
-
LO6: Apply a differentiated system of nomenclature for simple inorganic compounds: binary ionic compounds, binary ionic compounds containing transition metals, molecular compounds (covalent compounds), ionic compounds contaning polyatomic ions.
Representing Particles
- LO7: Represent atoms, ions, and molecules using particle diagrams.
