Ionic Compound Names and Formulas

Why is sodium acetate my favorite compound?

Nov 7­9:52 AM

Ionic Compound Names and Formulas

Goal: to unambiguously ...

• go from a name to a formula

• go from a formula to a name

Nov 18­8:44 AM

+ ­

Remember, ionic compounds are always made of two ions, a positive cation and a negative anion.

I'm attracted to her negativity!

Nov 18­8:44 AM

+ ­

Li F

Remember, ionic compounds are always made of two ions, a positive cation and a negative anion.

This is a binary compound because it's made of two elements.

Nov 18­8:44 AM

+ ­

Li NO3

But one or both ions can be made of more than one atom.

This is a ternary compound because it's made of more than two elements.

Nov 18­8:44 AM

Li NO3

­

This is a ternary compound because it's made of more than two elements.

This ion, that is made of multiple atoms is called a polyatomic ion!

Oct 24­10:53 AM

Polyatomic IonsAs the name implies, polyatomic ions are made of several atoms.  

• These atoms are joined by strong covalent bonds (which we'll study in another unit).  

• For now, just think of them as a group of atoms glued together that, as a group, have a charge.

Oct 24­10:53 AM

Polyatomic Ions

• Polyatomic ions are everywhere and are important.  

• The sooner you learn to recognize them, the easier your understanding of chemistry will be.

• You will need to memorize 10 of the most common (there are MANY more).

Oct 24­10:58 AM

The ten you need to know are:

Ammonium NH4 +1

Nitrate NO3 ­1

Chlorate ClO3 ­1

Permanganate MnO4 ­1

Acetate C2H3O2 ­1

Hydroxide OH ­1

Sulfate SO4 ­2

Carbonate CO3 ­2

Chromate CrO4 ­2

Phosphate PO4 ­3

Nov 11­7:27 AM Oct 24­11:16 AM

Polyatomic ions act just like single­atom ions.  They bond with ions of the opposite charge in the same way.

Ionic Compound Names and Formulas

ALL ionic compounds are made of two ions:

• a positive ion (cation)

• a negation ion (anion)

Nov 7­9:59 AM

To name a compound, simply list the cation name, then the anion name.

Naming compounds

Yes, it's that easy!

Nov 7­9:59 AM

Cation (positive ion) can be:

• a metal: name is the same as the atom

• a polyatomic ion (NH4+1): NEVER change the name of a polyatomic ion. 

Naming compounds+

Nov 7­9:59 AM

Cation (positive ion) can be:

• a metal: name is the same as the atom

[If the metal can have more than one charge (many transition metals) use Roman numerals in the name to indicate the charge.]

Naming compounds+

Nov 7­9:59 AM

Anion (negative ion) can be:

• a non­metal: change the ending to ­ide

• a polyatomic ion: NEVER change the name of a polyatomic ion. 

Naming compounds­

(You never need Roman numerals for anions)
