Naming Binary Ionic Compounds - tamaqua.k12.pa.us



Naming Binary Ionic CompoundsName the cation first, using the name from the periodic table:CaI2CalciumName the anion, changing the ending to -ideCaI2Calcium IodideNaming compounds containing Polyatomic ions(cation is the polyatomic)Name the cation first, using the name from the “polyatomic ion sheet”:NH4ClAmmoniumName the anion, changing the ending to -ideNH4Cl Ammonium chlorideNaming compounds containing Polyatomic ions(anion is the polyatomic)Name the cation first, using the name from the periodic tableCa(NO2)2CalciumName the anion using the name as it appears on the “polyatomic ion sheet”. Ca(NO2)2 Calcium NitriteNaming compounds containing Polyatomic ions(both are polyatomic)Name the cation first, using the name as it appears on the” polyatomic ion sheet”(NH4)2SO4AmmoniumName the anion using the name as it appears on the “polyatomic ion sheet”. (NH4)2SO4 Ammonium SulfateNaming compounds containing a Transition Element (Group 3-12, tin or lead)Name the cation first, using the name as it appears on the periodic table. You must include a roman numeral to distinguish the charge. The roman numeral is placed in parentheses.CuBr2Copper (II)Name the anion next. If it is a binary ionic compound change the ending to –ide. If it is a polyatomic ion , use the “polyatomic ion sheet” to name. CuBr2 Copper (II) BromideDetermining the charge on the transition element(group 3-12, tin or lead)Write the ionic charge of the ion you know (the anion)CuBr21-Do a “reverse cross-over” to determine the charge. *It will always be positive. These are metals and therefore form cations.Cu1 Br21-2+Cu1 Br21-Copper (II) ................
