Compound NaCl K2SO4 AlF3 Cation Na K Al Anion Cl SO4 F Agenda Warm Up – 7 minutes Cornell Style Notes/ Examples – 15 minutes Guided Practice – 12 minutes Independent Closing Practice -15 minutes – 3 minutes Ionic Compounds Cation Metals Anion NonMetals Polyatomic Ions Main Group Metals Any metal that is not a transition metal Check Point Is Silver (Ag) a main group metal? Check Point Is Magnesium (Mg) a main group metal? How to Name Ionic Compounds?? [with main group metals] Compound: NaCl Step 1 Write the elemental name of the cation. Example: Na+1 → Sodium How to Name Ionic Compounds?? [with main group metals] Compound: NaCl Step 2 Write the elemental name of the anion. Example: Cl-1 → Chlorine How to Name Ionic Compounds?? [with main group metals] Compound: NaCl Change the suffix of Step 3 the anion to “ide” the anion is a nonmetal Example: Chlorine Chloride IF How to Name Ionic Compounds?? [with main group metals] Compound: NaCl Step 4 Rewrite the name of the compound Example: Sodium Chloride Exception What if your anion is a polyatomic ion? Write the name as it is on your list of polyatomic ions. Example: NO3-1 → Nitrate Example: K2SO4 Cation → K + , Anion → SO4 -2 1. Write the elemental name of the cation: K +1 → Potassium 2. Write the name of the polyatomic ion: SO4 -2 → Sulfate Answer: Potassium Sulfate Guided Practice Teacher: 1. Will show the problem on the board Students: 1. 2. 3. Take 22 seconds to look at the chemical formula SILENTLY and compose your answer on the whiteboard. Take 38 seconds to speak with your shoulder partner to solve the problem and discuss how to do it When Mr. Ghosh says “Boards Up” all students should raise their whiteboards in the air #1 CaBr2 Calcium Bromide #2 KClO3 Potassium Chlorate #3 Al2O3 Aluminum Oxide #4 Be(CN)2 Beryllium Cyanide Independent Practice Practice Makes Perfect 85% Closing What type of compounds did we learn to name today? Warm Up: 4 Minutes Stay in your own seat Write the Learning Target You should be working SILENTLY How do you distinguish between a main group metal and a transition metal? What is one difference between a main group metal and a transition metal? Agenda Warm Up – 7 minutes Cornell Style Notes/ Examples – 15 minutes Guided Practice – 6 minutes Compound Closing Bingo -24 minutes – 1 minute “But Mr. Ghosh, HOW DO YOU KNOW THE CHARGES OF THOSE ELEMENTS IN THE MIDDLE” – ANONYMOUS STUDENT How to Name Ionic Compounds? [with transition metal] Example Step 1 FeO Determine if the cation is a main group metal or transition metal Transition Metal How to Name Ionic Compounds? [with transition metal] Example FeO Step 2 Write the name of the cation FIRST Iron Example: Iron( ) LEAVE AN OPEN PARENTHESIS NEXT TO THE NAME OF METAL What Goes in the Parenthesis? How do we know the oxidation number of Iron? Oxidation number of Iron Charges of Cation + Anion = 0 Fe O How to Name Ionic Compounds? [with transition metal] FeO Example Step 3 Example: Iron(II ) Place the charge of the transition metal in the parenthesis using roman numerals How to Name Ionic Compounds? Example [with transition metal] FeO Write the name of the anion CORRECTLY Step 4 Example: Oxide [Nonmetal → Change the suffix to –ide] [Polyatomic Ion- Name as is] How to Name Ionic Compounds? [with transition metal] FeO Example Step 5 Write the complete name. Example: Iron (II)Oxide Example 1: Cu2S3 Example 2: Ni(CO3)2 Guided Practice Teacher: 1. Will show the problem on the board Students: 1. 2. 3. Take 16 seconds to write the compound’s formula on paper, classify the compound, locate the different parts of the compound using the periodic table and polyatomic list. Take 33 seconds to speak with your shoulder partner to solve the problem and discuss how to do it Be ready to share the name of the compound when Mr. Ghosh says SWAG Let’s Try It V(OH)3 Take 33 seconds Vanadium (III) Hydroxide Let’s Try It MnCl3 Take 33 seconds Manganese (III) Chloride Let’s Try It K2S Take 33 seconds Potassium Sulfide Are you Ready? Compound Bingo Compound #1 KCl Potassium Chloride Compound #2 NaNO3 Sodium Nitrate Compound #3 CuF Copper (I) Fluoride Compound #4 AgNO3 Silver (I) Nitrate Compound #5 Mn(CO3)2 Manganese (IV) Carbonate Compound #6 ZnCl2 Zinc (II) Chloride Compound #7 Mg(OH)2 Magnesium Hydroxide Compound #8 RbI Rubidium Iodide Compound #9 CaO Calcium Oxide Compound #10 K2Cr2O7 Potassium Dichromate Compound #11 V3N2 Vanadium (II) Nitride Compound #12 Fe(CN)2 Iron (II) Cyanide Compound #13 Fe3(PO4)2 Iron (II) Phosphate Compound #14 CoBr2 Cobalt (II) Bromide Compound #15 Ba(ClO3)2 Barium Chlorate Compound #16 SrBr2 Strontium Bromide Compound #17 AlCl3 Aluminum Chloride Compound #18 (NH4)2O Ammonium Oxide Compound #19 TiS Titanium (II) Sulfide Compound #20 Ni2SO4 Nickel (I) Sulfate Compound #21 Fe2O3 Iron (III) Oxide Compound #22 Ca3(PO4)2 Calcium Phosphate Compound #23 Ba3N2 Barium Nitride Compound #24 Cs3P Cesium Phosphide Compound #25 RbMnO4 Rubidium Permanganate Compound #26 HgI2 Mercury (II) Iodide Compound #27 ScSO3 Scandium (II) Sulfite Compound #28 Cd(NO3)2 Cadmium (II) Nitrite Compound #29 Be(ClO4)2 Beryllium Perchlorate Compound #30 Ti2(Cr2O7)3 Titanium (III) Dichromate Closing What type of compounds did we learn to name today?
