Visualizing Ionic and Covalent Compounds

Unit 4: Compounds and Reactions Reading: Chapter 7

Working Mode: Pairs Guided Instructional Activity 4-3

Learning Objective: Relate the kind of compound, its formula and name to a visualization of its microscopic structure.

Keywords: ionic compound, molecular compound, chemical formula, formula unit, molecule.

Instructions: Each of the following atomic level diagrams represents a particular compound. Use the atomic key to determine the type of compound, the formula of the compound, and the name of the compound shown in the visualization.
