Ionic Compounds

Cation Anion

Metals Polyatomic Ions

Non-Metals

Main Group MetalsAny metal that is not a

transition metal

Is Silver (Ag) a main group metal?

Check Point

NO

Is Magnesium (Mg) a main group metal?

Check Point

YES

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 2Write the elemental

name of the anion.

Example: Cl-1 → Chlorine

Compound: NaCl

Step 3


Change the suffix of

the anion to “ide” IF

the anion is a

nonmetal

Example: Chlorine

Chloride

Compound: NaCl

Step 4


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: NO3-1 → Nitrate

Example: K2SO4

Cation → K + , Anion → SO4 -2

1. Write the elemental name of the cation:

2. Write the name of the polyatomic ion:

K +1 → Potassium

SO4 -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

“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 1Determine if thecation is a maingroup metal ortransition metal

Example FeO

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


Step 3

Place the charge of the transition metal in the parenthesis using roman numerals

Example FeO

Example: Iron(II )


Step 4

Write the name of the anion CORRECTLY

[Nonmetal → Change the suffix to –ide]

[Polyatomic Ion- Name as is]

Example FeO

Example: Oxide


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:

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
