Agenda • Warm Up – 7 minutes • Cornell Style Notes/ Examples – 15 minutes • Guided Practice – 12 minutes • Independent Practice -15 minutes • Closing – 3 minutes
Ionic Compounds Cation Anion Metals Non-Metals Polyatomic Ions
Main Group Metals Any metal that is not a transition metal
Check Point Is Silver (Ag) a main group metal? NO
Check Point Is Magnesium (Mg) a main group metal? YES
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 Write the elemental name of the anion. Example: Cl-1 → Chlorine Step 2
How to Name Ionic Compounds??[with main group metals] Compound: NaCl Step 3 Change the suffix of the anion to “ide” IF the anion is a nonmetal Example: Chlorine Chloride
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 K +1 → Potassium SO4 -2 → Sulfate Answer: Potassium Sulfate Cation→ K +, Anion → SO4 -2 Write the elemental name of the cation: Write the name of the polyatomic ion:
Guided Practice • Teacher: 1. Will show the problem on the board • Students: • Take 22seconds to look at the chemical formula SILENTLY and compose your answer on the whiteboard. • Take 38seconds 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?
Write the Learning Target Warm Up: 4 Minutes Stay in your own seat 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 – 6minutes • Compound Bingo -24minutes • Closing – 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] Step 1 Determine if the cation is a main group metal or transition metal Example FeO Transition Metal
How to Name Ionic Compounds? [with transition metal] Step 2 Write the name of the cationFIRST Iron LEAVE AN OPEN PARENTHESIS NEXT TO THE NAME OF METAL Example FeO Example: Iron( )
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] Step 3 Place the charge of the transition metal in the parenthesis using roman numerals Example FeO Example: Iron(II )
How to Name Ionic Compounds? [with transition metal] Step 4 Write the name of the anion CORRECTLY [Nonmetal→ Change the suffix to –ide] [Polyatomic Ion- Name as is] Example FeO Example: Oxide
How to Name Ionic Compounds? [with transition metal] Step 5 Write the complete name. Example FeO Example: Iron (II)Oxide
Example 1: Cu2S3
Example 2: Ni(CO3)2
Guided Practice • Teacher: 1. Will show the problem on the board • Students: • 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 33seconds 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 Take 33 seconds Vanadium (III) Hydroxide V(OH)3
Let’s Try It Take 33 seconds Manganese (III) Chloride MnCl3
Let’s Try It Take 33 seconds Potassium Sulfide K2S
