Good Morning! 11/27/2015 Starter: Did you go through the review? Today we are going to… –Go over the review. –Then take the test
On the test you will be given The Periodic Table Polyatomic Ions table Covalent Prefixes Metals with Multiple charges
Chemical Bonding and Reactions Review
Element # of Valence electrons NameCharge Carbon (C)4Carbon Doesn’t like to ionize Oxygen (O)6Oxide-2 Iodine (I)7Iodide Potassium (K) 1Potassium+1 Calcium (Ca)2Calcium+2
Section 2: Writing ionic compounds. Practice Calcium Oxide = CaO Both 2 Copper (I) Iodide = CuI Both 1 Lithium Bromide = LiBr Both 1 Magnesium Phosphide = Mg 3 P 2 Mg is +2, P is -3
Section 3: Naming ionic compounds: CrCl 3 = Chromium (III) Chloride –Chromium (II) Chloride is CrCl 2 CuBr = Copper (I) Bromide –Copper (II) Bromide is CuBr 2 FeO = Iron (II) Oxide –Iron (III) Oxide is Fe 2 O 3 MgS = Magnesium Sulfide
Section 4 & 5: Writing formulas and naming them. K and PO 4 = K 3 PO 4 Potassium Phosphate Mg and SO 4 = MgSO 4 Magnesium Sulfate NH 4 and SO 4 = (NH 4 ) 2 SO 4 Ammonium Sulfate Na and OH = NaOH Sodium Hydroxide
Section 6: Naming covalent compounds. Remember the prefixes and write the following examples: N 2 O N 2 O 5 CBr 4 CS 2 =Dinitrogen Monoxide =Dinitrogen Pentaoxide =Carbon Tetrabromide =Carbon DiSulfide
Section 7: Naming covalent compounds. Remember the prefixes and write the following examples: Tetracarbon Octobromide Trinitrogen hexasulfide Pentaphosphorus heptaoxide Sulfur Diodide =C 4 Br 8 =N3S6=N3S6 =P5O7=P5O7 =SI 2
