Instructive Power Point about the Seven Basic Types of Inorganic Molecules. Very important considering our final exam

1. THE SEVEN BASIC MOLECULES
INORGANIC CHEMISTRY

3. HOW DO WE RECOGNIZE THEM
SALTS • Metals and Non-Metals
ACIDS • Starts with H always. Then Non-Metal
HYDROXIDES • Metals and OH
METAL OXIDES • Metals and Oxygen only
NON-METAL OXIDES • Non-Metals and Oxygen
METAL HYDRIDES • Metal and Hydrogen
NON-METAL HYDRIDES • Non-Metal and Hydrogen

4. ACIDS
OXACID
H2SO4 • THEY HAVE
OXYGEN
HYDRACID
• THEY HAVE NO
OXYGEN
HBr

5. Non
Metals
C N O S
H P B F
Br I Cl He
Ar Ne Kr Rd

6. Metals
K Li Ca Rb
Cs Mg Fe Mg
Mn Cu Au Ag
Ti Hg Ba Cr

7. SALTS
NON-
METALS
METALS

8. EXAMPLES (Formula and Name)
NaCl •Sodium Chloride
K2S •Potassium Sulfide
CaF2 •Calcium Fluoride
LiBr •Lithium Bromide

9. Rule:
Metals are writen first, because they
are the less eletronegative. Name
with no changes
Non-Metals are writen after. Mames
with the sufix «ide» instead of the
original
