9 Agenda  Warm Up – 7 minutes  Cornell Style Notes/ Examples – 15 minutes  Guided Practice – 12 minutes  Independent Practice -15 minutes  Closing – 3 minutes

10 Ionic Compounds Cation Anion Metals Polyatomic Ions Non- Metals

11 Main Group Metals Any metal that is not a transition metal

12 Is Silver (Ag) a main group metal? Check Point

13 Is Magnesium (Mg) a main group metal? Check Point

14 Step 1 How to Name Ionic Compounds?? [ with main group metals] Write the elemental name of the cation. Example: Na +1 → Sodium Compound: NaCl

15 How to Name Ionic Compounds?? [ with main group metals] Step 2 Write the elemental name of the anion. Example: Cl -1 → Chlorine Compound: NaCl

16 Step 3 How to Name Ionic Compounds?? [ with main group metals] Change the suffix of the anion to “ide” IF the anion is a nonmetal Example: Chlorine Chloride Compound: NaCl

17 Step 4 How to Name Ionic Compounds?? [ with main group metals] Rewrite the name of the compound Example: Sodium Chloride Compound: NaCl

18

19 Exception  What if your anion is a polyatomic ion?  Write the name as it is on your list of polyatomic ions.  Example: NO 3 -1 → Nitrate

20 Example: K 2 SO 4 Cation → K +, Anion → SO 4 -2 1. Write the elemental name of the cation: 2. Write the name of the polyatomic ion: K +1 → Potassium SO 4 -2 → Sulfate Answer: Potassium Sulfate

21 Guided Practice  Teacher: 1. Will show the problem on the board  Students: 1. Take 22 seconds to look at the chemical formula SILENTLY and compose your answer on the whiteboard. 2. Take 38 seconds to speak with your shoulder partner to solve the problem and discuss how to do it 3. When Mr. Ghosh says “Boards Up” all students should raise their whiteboards in the air

22 CaBr 2 Calcium Bromide #1

23 KClO 3 Potassium Chlorate #2

24 Al 2 O 3 Aluminum Oxide #3

25 Be(CN) 2 Beryllium Cyanide #4

26 Independent Practice Practice Makes Perfect 85%

27 Closing What type of compounds did we learn to name today?

28 Warm Up: 4 Minutes Write the Learning Target You should be working SILENTLY Stay in your own seat 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?

29 Agenda  Warm Up – 7 minutes  Cornell Style Notes/ Examples – 15 minutes  Guided Practice – 6 minutes  Compound Bingo -24 minutes  Closing – 1 minute

30 “But Mr. Ghosh, HOW DO YOU KNOW THE CHARGES OF THOSE ELEMENTS IN THE MIDDLE” – ANONYMOUS STUDENT

31 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

32 How to Name Ionic Compounds? [with transition metal] Step 2  Write the name of the cation FIRST Iron  LEAVE AN OPEN PARENTHESIS NEXT TO THE NAME OF METAL Example FeO Example: Iron( )

33 What Goes in the Parenthesis? Oxidation number of Iron  How do we know the oxidation number of Iron ? Charges of Cation + Anion = 0 Fe O

34 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 )

35 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

36 How to Name Ionic Compounds? [with transition metal ] Step 5  Write the complete name. Example FeO Example: Iron (II)Oxide

37 Example 1: Cu 2 S 3

38 Example 2: Ni(CO 3 ) 2

39 Guided Practice  Teacher: 1. Will show the problem on the board  Students: 1. 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. 2. Take 33 seconds to speak with your shoulder partner to solve the problem and discuss how to do it 3. Be ready to share the name of the compound when Mr. Ghosh says SWAG

40 Let’s Try It V(OH) 3 Take 33 seconds Vanadium (III) Hydroxide
