NomenclatureNomenclature• A System of Naming Compounds• Compounds are two or more
atoms of different elements bonded together.
• Even though the gases O2, N2, F2, and Cl2 travel in pairs, their names are simply oxygen, nitrogen, fluorine, and chlorine.

Practice 1Practice 1• S2O2
• Disulfur dioxide
• Remember (Do not use mono if only 1 atom on first element)

Rules for naming AcidsRules for naming Acids
![Page 9: Use the talents you possess; for the woods would be very silent if no birds sang except the best.](https://reader030.fdocuments.us/reader030/viewer/2022032517/56649cc25503460f949897ed/html5/thumbnails/9.jpg)
Rule 1Rule 1• When anion (X) ends with (ide).
Acid name begins with hydro change the ide to (ic), then follow by the word acid.
• Hydro ____ ic Acid
• Ex: HCl • Hydrochloric acid • [X = chloride]
![Page 10: Use the talents you possess; for the woods would be very silent if no birds sang except the best.](https://reader030.fdocuments.us/reader030/viewer/2022032517/56649cc25503460f949897ed/html5/thumbnails/10.jpg)
Rule 2Rule 2• When anion ends in (ite), change
the stem of the anion with the suffix (ous) followed by the word acid.
• ite to ous
• Ex: H2SO3
• Sulferous acid
• [X = sulfite]

Rule 3Rule 3• If anion ends in (ate), the acid
name is the stem of the anion with the suffix (ic) followed by the word acid.
•ate to ic
• Ex: HNO3 • Nitric Acid• [ X = nitrate]
