Naming Covalent and Ionic Compounds

Naming Covalent and Ionic Compounds

Let's recap!

You will need your:

- periodic table

- polyatomic ion list

-Unit 4 notes

When naming or writing compounds, the first step is to determine if the compound is ionic or covalent.

What is the difference?

Multiple Choice

Identify the following compound as ionic or covalent: SO₂

• ionic

• covalent

Multiple Choice

Identify the following compound as ionic or covalent: CF₄

• ionic

• covalent

Multiple Choice

A bond between a metal and a nonmetal is called a(n)

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Multiple Choice

A bond between a nonmetal and a nonmetal is called a(n)

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Multiple Choice

Identify the following compound as ionic or covalent: Na₂SO₄

• ionic

• covalent

Multiple Choice

Identify the following compound as ionic or covalent: MgO

• ionic

• covalent

So what do we do after we determine if it is an ionic or covalent compound?

We use the rules depending on what type of compounds. Follow the flow chart in the next slide.

After you decide whether the following compounds are ionic or covalent, follow the flow chart or notes to name or write formulas.

You can always go back to view slides!

Wait!!!! I just wanted to remind you...

• Ionic compounds: NO PREFIXES. Transitions need roman numeral. NO PREFIXES. Keep polyatomic name the same. NO PREFIXES

• Covalent compounds: NO CHARGES. You use the prefixes!

• BOTH: Criss cross charges to get subscripts (top cross over to bottom).
