2. Naming Compounds Organic Check 1st Element Ionic Molecular Acid
-if you have C and H
Check 1st Element
-if it’s a metal
-if it’s a H
-if it’s a nonmetal
Ionic
Molecular
Acid
Split into ions
*Name elements from left to right using the periodic table
*use prefixes to tell how many
*end in -ide
-ide(anion),
hydro____ic acid
-ate(anion),
____ic acid
Check charge for transition metals
-ite(anion),
____ous acid
Cation- same as element
Anion- -ide or polyatomic
# of H’s match the charge of the anion
Put together ions so net charge is 0

3. Practice Part 1 FeS First element is a metal, so it is ionic
Cation would be iron
Anion would be sulfide
Iron (II) sulfide
NCl3
First element is a nonmetal, so it is molecular
Nitrogen trichloride

4. Practice Part 1 (cont.) CoSO4 First element is a metal
Cobalt (II) Sulfate
H3PO3
First element is H, so it is an acid
Normally would end in -ite, so should be an -ous acid
Phosphorous acid

5. Practice Part 2 potassium sulfide
First element is a metal, so it is ionic
Potassium ion is K+
Sulfide ion is S2-
To balance charges it should be K2S
Hydrobromic acid
Its is a hydro __ic acid, so it should end with -ide
Bromide has a -1 charge
HBr

6. Practice Part 2 (cont.) Tin (IV) chloride
Starts with a metal, so it is ionic
(IV) means tin has a +4 charge
Chloride has a -1 charge
SnCl4
Dinitrogen pentoxide
Uses prefixes so it is molecular
Di means it has 2 nitrogens
Pent means it has 5 oxygens
N2O5
