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

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.)

Chemical Nomenclature Write the formula of the following covalent compounds. Be sure to learn and use the correct formulas for the alkanes such as methane. 1. Bromine dioxide 2. Carbon disulfide 3. Butane 4. Diphosphorus trisulfide 5. Carbon tetrachloride 6. Propane 7. Bromine pentafluoride 8. Sulfur trioxide 9. Hexane 10. Dichlorine monoxide 11. Dichlorine monoxide 12. Carbon tetrachloride
