  8. Ionic Compounds the sum of all oxidation numbers in a neutral species is zero, 0,

  9. Ionic Compounds the sum of all oxidation numbers in a neutral species is zero, 0,

  10. 1 1 TM+ roman numeral 1 2 2 1 1 2 A Roman numeral represents oxidation state: The larger the positive number, The higher the oxidation state of the ion. Only transition metals and heavier post-transition metals (e.g. Sn,Pb) use a Roman numeral in its name Ionic Compounds the sum of all oxidation numbers in a neutral species is zero, 0,

  11. Ion charge calculation in ionic substances 1) Ion charge is called “oxidation state or number” 2) memorize the monatomic ions and their charge the “–ides” (C4- , N3- , O2- , F1- ). 3) memorize the polyatomic ions and their charge “–ates”( [PO4]3- , [SO4]2- , [ClO4]1- ) 4) All anions (-ides and -ates) seek out positively charged cations ( Na1+, Ca2+, Al3+ ) to achieve a balance of zero in overall substance charge.

  12. SO4 Na Na SO4 2- Na Na SO4 2- Na Na 1+ 1+ 1 + (2-) + 1 = 0 Perhaps the easiest way to calculate an oxidation number for a metal in an ionic compound is to draw a visual. For example, Na2SO4 1) Separate the metal from the nonmetals in the formula, 2) Assign monatomics and polyatomics whose oxidation number was memorized, 3) Knowing the sum of all oxidation numbers in a neutral species is zero (0), solve for the oxidation number of the remaining element. sodium sulfate

  13. PO4 Fe PO4 3- Fe Na PO4 3- Fe Na 1+ 3+ 3 + (3-) = 0 Calculate an oxidation number for a metal in an ionic compound of FePO4 1) Separate the metal from the nonmetals in the formula, 2) Assign monatomics and polyatomics whose oxidation number was memorized, 3) Knowing the sum of all oxidation numbers in a neutral species is zero (0), solve for the oxidation number of the remaining element. iron (III) phosphate

  14. PO4 PO4 PO4 PO4 PO4 PO4 3- 3- 3- 3- Fe Fe Fe 2+ Fe Fe Fe 2+ Fe Fe Fe 2+ Calculate an oxidation number for a metal in an ionic compound of Fe3(PO4)2 1) separate the metal from the nonmetals in the formula, 2) Assign monatomics and polyatomics whose oxidation number was memorized, 3) Knowing the sum of all oxidation numbers in a neutral species is zero (0), solve for the oxidation number of the remaining element. iron (II) phosphate 2 + (3-) + 2 + (3-) + 2 = 0
