SNC2DName: : PolyatomicCompounds ExerciseDate:Determine the common attributes of the following compounds.Polyatomic CompoundsThese are polyatomic compoundsFeSO4= iron (II) sulfatePb3(PO4)4= lead (IV) phosphateAgNO3= silver nitrateNa2CO3= sodium carbonateLiC2H3O2= lithium acetateThese are not polyatomiccompoundsH2= hydrogenH2O = dihydrogen monoxideNa3P = sodium phosphideNi3N2= nickel (II) nitrideH3N = hydronitric acidWhat is true of all polyatomic compounds that are not true for all othercompounds?Polyatomic compounds consist of a group of atoms (more than 2 atoms) covalentlybonded together. These compounds hold a net charge, so they exist as ions, whichisn’t true for the other compounds.Determine the rule(s) for naming polyatomic compounds. Generally, the ion namewill end in “ite”, or “ate”.The cation is written first, then the anion.Determine the rule(s) for writing formulas for polyatomic compounds.The cation comes first in the name, then the anion comes second. If the samepolyatomic ion is in the formula unit more than once, then parentheses are addedalong with the subscript outside of the parentheses.
Polyatomic DerivativesThese are polyatomic derivatives.Li3PO3= lithium phosphiteMg(NO4)2= magnesium pernitrateFe(ClO)3= iron (III) hypochloriteCu2SO3= copper (I) sulfiteThese are normal polyatomic compounds.Li3PO4= lithium phosphateMg(NO3)2= magnesium nitrateFe(ClO3)3= iron (III) chlorateCu2SO4= copper (I) sulfateWhat is true of all polyatomic derivatives that are not true for all normalpolyatomic compounds?Determine the rule(s) for naming polyatomic derivatives compounds.Determine the rule(s) for writing formulas for polyatomic derivatives compounds.
