Nomenclature (A fancy way to say Naming) PO 4 3- phosphate ion C 2 H 3 O 2 - acetate ion

Predicting Charges on Monatomic Ions KNOW THESE !!!! Cd +2 C +/- 4

NO 3 - nitrate ion NO 2 - nitrite ion Polyatomic Ions

You can make additional polyatomic ions by adding a H + to the ion! CO 3 -2 is carbonate HCO 3 – is hydrogen carbonate H 2 PO 4 – is dihydrogen phosphate HSO 4 – is hydrogen sulfate Polyatomic Ions

Two Families of Compounds: Ionic Binary (with and without transition metal) Ternary Molecular

Compounds IonicMolecular

CATION -- Metal (POSITIVELY CHARGED ION) + ANION -- Nonmetal (NEGATIVELY CHARED ION)  COMPOUND CATION -- Metal (POSITIVELY CHARGED ION) + ANION -- Nonmetal (NEGATIVELY CHARED ION)  COMPOUND A neutral compound What is an ionic compound? Na + + Cl -  NaCl

CompoundsIonic Binary (2 elements) With Common Ions With Transition Metal Ternary (3 or more elements) Molecular

Binary Ionic Compounds Two elements (one metal and one nonmetal; without transition metal) Naming: Use name of metal, then put in name of nonmetal with ‘ide’ as the suffix. Calcium fluoride Ca F - ---> CaF 2

Naming Binary Ionic Compounds Examples: NaCl ZnI 2 Al 2 O 3 sodium chloride zinc iodide aluminum oxide

Learning Check Write the correct formula for the compounds containing the following ions: 1. Na +, S 2- a) NaS b) Na 2 Sc) NaS 2 2. Al 3+, Cl - a) AlCl 3 b) AlCl c) Al 3 Cl 3. Mg 2+, N 3- a) MgN b) Mg 2 N 3 c) Mg 3 N 2

CompoundsIonic Binary (2 elements) With Common Ions With Transition Metal Ternary (3 or more elements) Molecular

Binary Ionic Compounds Two elements (one metal and one nonmetal; with transition metal) Naming: Use name of metal, then put in name of nonmetal with ‘ide’ as the suffix. **Difference** Must input Roman Numerals Manganese (II) Chloride Mn Cl -  MnCl 2

Transition Metals Elements that can have more than one possible charge MUST have a Roman Numeral to indicate the charge on the individual ion. 1+ or or 3+ Cu +, Cu 2+ Fe 2+, Fe 3+ copper(I) ion iron(II) ion copper (II) ion iron(III) ion Transition metals (except Ag, Zn, Cd, and Al) require a Roman Numeral.

Learning Check Complete the names of the following binary compounds with variable metal ions: FeBr 2 iron (_____) bromide CuClcopper (_____) chloride SnO 2 _______ ( _____ ) __________ Fe 2 O 3 _______ ( _____ ) __________ Hg 2 S_______ ( _____ ) __________

CompoundsIonic Binary (2 elements) With Common Ions With Transition Metal Ternary (3 or more elements) Molecular

An ionic compound with a polyatomic ion! Carbonate Sulfate Nitrate Ammonium Acetate Hydroxide Ternary Ionic Compounds

Naming Ternary Compounds Contains at least 3 elements There MUST be at least one polyatomic ion (it helps to circle the ions) Examples: NaNO 3 Sodium nitrate K 2 SO 4 Potassium sulfate Al(HCO 3 ) 3 Aluminum bicarbonate or Aluminum hydrogen carbonate

Ternary Ionic Nomenclature Sodium Sulfate Na + and SO 4 -2 Na 2 SO 4 Iron (III) hydroxide Fe +3 and OH - Fe(OH) 3 Ammonium carbonate NH 4 + and CO 3 –2 (NH 4 ) 2 CO 3

Learning Check 1. aluminum nitrate a) AlNO 3 b) Al(NO) 3 c) Al(NO 3 ) 3 2. copper(II) nitrate a) CuNO 3 b) Cu(NO 3 ) 2 c) Cu 2 (NO 3 ) 3. Iron (III) hydroxide a) FeOHb) Fe 3 OHc) Fe(OH) 3 4. Tin(IV) hydroxide a) Sn(OH) 4 b) Sn(OH) 2 c) Sn 4 (OH)
