1 Names 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 H H Li Be B C N O F Na Mg Al Si P S Cl K Ca Rb Cs Cu Zn Ga Ge As Se Br Sr Ag Cd In Sn Sb Te I Ba Au Hg Tl Pb Bi Ti Cr Mn Fe Co Ni Polyatomic Ions Fill in the name of each ion Formula OH 1 CN 1 SCN 1 HCO3 1 HSO3 1 HSO4 1 C2H3O2 1 NO2 1 NO3 1 MnO4 1 ClO 1 ClO2 1 ClO3 1 ClO4 1 Name Formula O2 2 CO3 2 SO3 2 SO4 2 S2O3 2 C2O4 2 CrO4 2 Cr2O7 2 PO3 3 PO4 3 NH4 1 Hg2 2 Name At 8A 2 Polyatomic Ions continued Fill in the formula and charge of each ion Formula Name Hydroxide Cyanide Thiocyanate Bicarbonate Hydrogen Carbonate Bisulfite Hydrogen Sulfite Bisulfate Hydrogen Sulfate Acetate Nitrite Nitrate Permanganate Hypochlorite Chlorite Chlorate Perchlorate Formula Name Peroxide Carbonate Sulfite Sulfate Thiosulfate Oxalate Chromate Dichromate Phosphite Phosphate Ammonium Mercury I
