1. Naming Ionic Compounds
I didn’t
Catch your name.
Name the cation (monatomic or polyatomic), add Roman Numeral if a transition metal
Add the suffix –ide to the anion if monatomic. Name the Polyatomic.
Bond,
Ionic Bond

2. Writing Ionic Compounds
Take the charge number on metal make it subscript on non-metal
Take the charge on the non-metal and make it subscript on metal
ALWAYS REDUCE

3. Naming Acids
All acids are characterized by beginning their molecular formula with the hydrogen (H) atom.
HCl, H2SO4, HNO3, HI, HF, HC2H3O2
That is because a H+ is given off when it is dissolved (disassociates) in water.

4. Naming Acids Acids that end with the suffix –ate.
Replace with the –ic suffix
HNO3 hydrogen nitrate
Nitric Acid
Just remember, I –ate something –ic(ky).

5. Naming Acids Acids that end with the suffix –ite.
Replace with the suffix –ous.
HClO2 hydrogen chlorite
Chlorous acid
–ite is said by –ous.

6. Naming Acids
We will use the prefix hydro- and suffic –ic if the anion ends in –ide
If it ends in –ide put hydro- (d=d)
HCl hydrogen chloride would be hydrochloric acid HF HI
HBr

7. Prefixes Mono-1 Di-2 Tri-3 Tricycle has 3 wheels Tetra-4
Penta-5 Pentagon has 5 sides
Hexa-6 six has an x and so does hexa-
Hepta-7
Octa-8 Octopus has 8 arms
Nona-9 Nona- and Nine begin with N’s
Deca-10 Remember 10 years in a decade

8. Practice Naming Molecular Compounds
NO2
Nitrogen Dioxide
CO3
Carbon Trioxide
P3Cl5
Triphosphorus pentachloride
S4Br10
Tetrasulfur decabromide

9. Naming Molecular Compounds
Rules are the same for naming the first and second atoms. There are no polyatomic ions or Roman numerals. Remember, Molecules are two non-metals
Prefixes are added to the beginning of the atoms name according to its subscript #
The prefixes are the same as for the hydrates

10. Let’s Practice
HCl
H2SO4
HNO3
HNO2
HC2H3O2
H2CO3 HF
