Ionic Compounds Cation Anion Metals Polyatomic Ions Non- Metals

Main Group Metals Any metal that is not a transition metal

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

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

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

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

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

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

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

Example: K 2 SO 4 Cation → K +, Anion → SO 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

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

CaBr 2 Calcium Bromide #1

KClO 3 Potassium Chlorate #2

Al 2 O 3 Aluminum Oxide #3

Be(CN) 2 Beryllium Cyanide #4

Independent Practice Practice Makes Perfect 85%

“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 cation FIRST Iron  LEAVE AN OPEN PARENTHESIS NEXT TO THE NAME OF METAL Example FeO Example: Iron( )

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

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: Cu 2 S 3

Example 2: Ni(CO 3 ) 2

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

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

Let’s Try It MnCl 3 Take 33 seconds Manganese (III) Chloride

Let’s Try It K2SK2S Take 33 seconds Potassium Sulfide
