  1. Highland Science Department Ionic Nomenclature

  2. Highland Science Department Ionic Nomenclature the more metallic element always comes first

  3. Highland Science Department Ionic Nomenclature Multivalent Ions: metals with more than one common valence -the possible valences are indicated on your periodic table

  4. Highland Science Department Ionic Nomenclature Multivalent Ions: metals with more than one common valence -the possible valences are indicated on your periodic table Polyatomic Ions: groups of atoms that behave as a single ion

  5. Highland Science Department Ionic Nomenclature Polyatomic Ions: acetate CH3COO1- ammonium NH41+ hydroxide OH1- cyanide CN1- permanganate MnO41- thiocyanate SCN1- hydrogen carbonate HCO31- (bicarbonate)

  6. Highland Science Department Polyatomic Ions from oxy-acids

  7. Highland Science Department Polyatomic Ions from oxy-acids

  8. Highland Science Department Polyatomic Ions from oxy-acids

  9. Highland Science Department Polyatomic Ions from oxy-acids

  10. Highland Science Department Polyatomic Ions from oxy-acids NICK the CAMEL had a CLAM for SUPPER in PHOENIX 1. First letter(s) indicates name e.g. NICK = nitrate

  11. Highland Science Department Polyatomic Ions from oxy-acids NICK the CAMEL had a CLAM for SUPPER in PHOENIX 1. First letter(s) indicates name e.g. NICK = nitrate 2. # of consonants indicates # of oxygen e.g. NICK has 3 = NO3

  12. Highland Science Department Polyatomic Ions from oxy-acids NICK the CAMEL had a CLAM for SUPPER in PHOENIX 1. First letter(s) indicates name e.g. NICK = nitrate 2. # of consonants indicates # of oxygen e.g. NICK has 3 = NO3 3. # of vowels indicates valence e.g. NICK has 1 = NO31-

First letter(s) indicates name e.g. NICK = nitrate 2. # of consonants indicates # of oxygen e.g. NICK has 3 = NO3 3. # of vowels indicates valence e.g. NICK has 1 = NO31- -add an oxygen to any to get "per-ate" -subtract an oxygen to get "ite" -subtract two oxygens to get "hypo-ite"

  14. Highland Science Department Formula Writing:criss cross method kris kross 1. Write the valences (oxidation numbers) beside each ion as superscripts e.g. magnesium oxide Mg2+ O2-

  15. Highland Science Department Formula Writing:criss cross method 1. Write the valences (oxidation numbers) beside each ion as superscripts e.g. magnesium oxide Mg2+ O2- 2. Cross the valences (without charge) to the pairing atom and write as subscripts Mg2 O2

  16. Highland Science Department Formula Writing:criss cross method 1. Write the valences beside each ion as subscripts e.g. magnesium oxide Mg2+ O2- 2. Cross the valences (without charge) to the pairing atom and write as subscripts Mg2 O2 3. Reduce the subscripts to their lowest forms Mg1 O1

  17. Highland Science Department Formula Writing:criss cross method 1. Write the valences beside each ion as subscripts e.g. magnesium oxide Mg2+ O2- 2. Cross the valences (without charge) to the pairing atom and write as subscripts Mg2 O2 3. Reduce the subscripts to their lowest forms Mg1 O1 4. Do not write ones; they are understood Mg O

  18. Highland Science Department Formula Writing:criss cross method 1. Write the valences beside each ion as subscripts e.g. magnesium oxide Mg2+ O2- 2. Cross the valences (without charge) to the pairing atom and write as subscripts Mg2 O2 3. Reduce the subscripts to their lowest forms Mg1 O1 4. Do not write ones; they are understood Mg O * For polyatomic ions, place the ion in brackets before writing the subscript

  19. Highland Science Department Formula Writing:criss cross method Try these: 1. sodium fluoride 2. lithium oxide 3. beryllium sulfide 4. calcium chloride 5. ammonium iodide 6. magnesium carbonate

  20. Highland Science Department Formula Writing:criss cross method Try these: 1. sodium fluoride NaF 2. lithium oxide Li2O 3. beryllium sulfide BeS 4. calcium chloride CaCl2 5. ammonium iodide NH4I 6. magnesium carbonate MgCO3

  21. Highland Science Department Naming: -metal is named first -non-metal is named second with its ending changed to "ide" for binary (2 element) molecules

  22. Highland Science Department Naming: -metal is named first -non-metal is named second with its ending changed to "ide" for binary (2 element) molecules -reverse criss cross sorts out the valence of a multi-valent ion e.g. FeO vs. Fe2O3 Fe1+ O1- Fe3+ O2- -oxygen can only be O2- so... Fe2+ O2- Fe3+ O2- double them both

  23. Highland Science Department Naming: -metal is named first -non-metal is named second with its ending changed to "ide" for binary (2 element) molecules -reverse criss cross sorts out the valence of a multi-valent ion e.g. FeO vs. Fe2O3 Fe1+ O1- Fe3+ O2- -oxygen can only be O2- so... Fe2+ O2- Fe3+ O2- double them both -the multi-valent ion valence is written in Roman numerals in brackets after the name iron (II) oxide iron (III) oxide

  24. Highland Science Department Naming: Roman numeral FYI I = 1 II = 2 III = 3 IV = 4 V = 5 VI = 6 VII = 7 VIII = 8 *the pattern: I's placed after add to the value, I's placed before subtract

  25. Highland Science Department Naming: the same pattern holds true for bigger numbers X = 10 L = 50 C = 100 M = 1000 2013 MMXIII 1997 MCMXCVII

  26. Highland Science Department Naming: the same pattern holds true for bigger numbers X = 10 L = 50 C = 100 M = 1000 2013 MMXIII 1997 MCMXCVII Imagine doing scientific notation... ...or just thank the Middle East for Arabic numerals
