  1. Writing NAMES & FORMULAS FOR POLYATOMIC IONS & RELATED OXYACIDS Textbook Pages: 66 – 67, 69 - 70

  2. Polyatomic Ions • Definition: A polyatomic ion is a group of atom that stay together and have an overall ionic charge. • Example: NO3− Nitrate ion • ***Refer to the back of your Periodic Table for a list of the Polyatomic Ions!!!

  3. The “Standard” Polyatomic Ions • There is a special way to name these ion. The following are the most common forms of the ions: • The Standards: Polyatomic Ions: • ClO3 - chlorate ion • BrO3 – bromate ion • IO3 - iodate ion • NO3 - nitrate ion • SO4 2− sulphate ion • CO3 2− carbonate ion • PO4 3− phosphate ion ***All “standard” polyatomic ions end in “ate”

  4. Altering the Number of Oxygens in Polyatomics • 1. If there is one more Oxygen than the standard ion, the ion follows the following pattern: • Example: ClO4−perchlorate • Note: the charge does not change, it stays the same as the standard/original polyatomic ion. per ________ ate

  5. Altering the Number of Oxygens in Polyatomics • If there is one less Oxygen then the standard ion, the ion follows the following pattern: • Example: ClO2− chlorite • Note: the charge does not change, it stays the same as the standard/original polyatomic ion. ________ ite

  6. Altering the Number of Oxygens in Polyatomics • 3. If there are two lessOxygen than the standard ion, then the ion follows the following pattern: • Example: ClO−hypochlorite • Note: the charge does not change, it stays the same as the standard/original polyatomic ion. hypo ________ ite

  7. Oxyacids • Definition: Oxyacid is an acid composed of hydrogen, oxygen, and atoms of at least one other element. • Oxyacids follow the pattern: ic acid • Example: HClO3 Chloric Acid

  8. Oxyacids • There is a special way to name these acids. • The Standards: Oxyacids (Add H+): • HClO3 chloricacid • HBrO3 bromicacid • HIO3 iodicacid • HNO3 nitricacid • H2SO4 sulphuricacid • H2CO3 carbonicacid • H3PO4 phosphoricacid ***All “standard” oxyacids take the format : ______ ic acid

  9. Altering the Number of Oxygens in Oxyacids • 1. If there is one moreOxygen that the standard, the acid follows the following pattern: • Example: HClO4perchloric acid per ________ ic acid

  10. Altering the Number of Oxygens in Oxyacids • 2. If there is one lessOxygen that the standard, the acid follows the following pattern: • Example: HClO2 chlorous acid ________ ous acid

  11. Altering the Number of Oxygens in Oxyacids • If there are two less Oxygen than the standard, the acid follows the following pattern: • Example: HClO hypochlorous acid hypo ________ ous acid
