1. Chemical Nomenclature Ionic compounds: Compounds are electrically neutral. Ca 2+ F - (X 2) Formula: CaF 2 Name: Calcium Fluoride F - Ca 2+ NO 3 - (X 2) Formula: Ca(NO 3 ) 2 Name: Calcium nitrate NO 3 - Na + NO 3 - Formula: NaNO 3 Name: Sodium nitrate NOTE: Na(NO 3 ) is incorrect. Do not use parentheses in this formula. H + S 2- Formula: H 2 S Name: Hydrogen sulfide In water: Hydrosulfuric acid (Binary acid - Text pages 94-96) H + SO 4 2- Formula: H 2 SO 4 Name: Hydrogen sulfate In water: Sulfuric acid (Oxyacid – Text page 95-96) Alkanes: See base names - text page 115

4. Chemical Nomenclature Covalent compounds: There are 7 covalent, diatomic gases: H 2, O 2, N 2, F 2, Cl 2, Br 2, and I 2. The Prefixes for other covalent compounds: 1=mono- 2=di- 3 = tri- 4 = tetra- 5 = penta- 6 = hexa- 7 = hepta- 8 = octa- Example: S 2 Cl 2 is Disulfur dichloride. CO is carbon monoxide (“mono” is often dropped for the first element in the compound-never for other elements.)
