Unit 3: Chemical Bonding

Learning Objectives:

PSc.2.2.2 Infer the type of chemical bond that occurs, whether covalent, ionic, or metallic, in a given substance.

• Describe how ionic, covalent, and metallic bonds form and provide examples of substances that exhibit each type of bonding.
• Predict the type of bond between two elements in a compound based on their positions in the periodic table.

PSc.2.2.3 Predict chemical formulas and names for simple compounds based on knowledge of bond formation and naming conventions.

• Name and write formulas for simple binary compounds containing a metal and nonmetal using representative elements (A Groups or 1, 2, 13-18) and compounds involving common polyatomic ions: ammonium (NH₄⁺), acetate (C₂H₃O2⁻), chlorate (ClO3⁻), nitrate (NO3⁻), hydroxide (OH⁻), carbonate (CO32⁻), sulfate (SO42⁻), phosphate (PO43⁻).
• Name and write formulas for binary compounds of two nonmetals using Greek prefixes (mono-, di-, tri-, tetra-, etc.).
