Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. Nomenclature Warm-up #6. . Identify these compounds as ionic or covalent, then name them. Remember to use Roman numerals when necessary!. ____ (I or C) 1. V. 3. As. 2. ____ (I or C) 2. Hg. 3. P. ____ (I or C) 3. .

Write the name and formula for an ionic compound containing a polyatomic ion.. Polyatomic Ions. INORGANIC Nomenclature Nomenclature - Humor “Ferrous Wheel” Fe = iron (Latin = ferrum) Fe 2+ = lower oxidation state = ferr ous Fe 3+ = higher oxidation state = ferr ic BaNa 2 “ BaNaNa Oxyanions. Oxyanions- negative ions containing oxygen.. These have the suffix “-ate” or “-ite”. “-ate” means it has more oxygen atoms bonded, “-ite” has less. For example. SO. 4. 2-. sulfate. HOMEWORK.
