Monatomic Ions1Names, Charges, and Formulas of Common Ions: Student Practice Sheet This is a tool to help you study the ions. You need to memorize the charges on all the common monatomic ions as well as the names, charges, and formulas for the common polyatomic ions. This worksheet includes the same tables of ions you have in your nomenclature lab, but critical information has been deleted so you can fill it in yourself. Consider it a practice test to let you know which ions you need to study more. Monatomic Ions Fill in the charge each element would have if it were an ion. If the element does not form ions, do not include a charge. If the element forms two common ions of different charge, list both charges. 1A 2A 3A 4A 5A 6A 7A 8A H H Li Be B C N O F Na Mg Al Si P S Cl K Ca Ti Cr Mn Fe Co Ni Cu Zn Ga Ge As Se Br Rb Sr Ag Cd In Sn Sb Te I Cs Ba Au Hg Tl Pb Bi At Polyatomic Ions Fill in the name of each ion: Formula Name Formula Name OH-1 O2-2 CN-1 CO3-2 SCN-1 SO3-2 HCO3-1 SO4-2 HSO3-1 S2O3-2 HSO4-1 C2O4-2 C2H3O2-1 CrO4-2 NO2-1 Cr2O7-2 NO3-1 MnO4-1 PO3-3 ClO-1 PO4-3 ClO2-1 ClO3-1 NH4+1 ClO4-1 Hg2+22 Polyatomic Ions, (continued) Fill in the formula and charge of each ion: Formula Name Formula Name Hydroxide Peroxide Cyanide Carbonate Thiocyanate Sulfite Bicarbonate (Hydrogen Carbonate) Sulfate Bisulfite (Hydrogen Sulfite) Thiosulfate Bisulfate (Hydrogen Sulfate) Oxalate Acetate Chromate Nitrite Dichromate Nitrate Permanganate Phosphite Hypochlorite Phosphate Chlorite Chlorate Ammonium Perchlorate Mercury
