Assigning Oxidation Numbers
Use these rules in order.
The sum of all oxidation numbers of all elements = charge on substance.
Oxidation Number:
Examples:
1. Atoms in their elemental state
Fe, H2, O2
2. Monatomic ions
= charge
F, Fe3+
IN COMPOUNDS
NaCl, KNο
3. Group 1A
4. Group 2A
5. Fluorine
+1
+2
MgO
-1
HF, CIF
6. Hydrogen
7. Oxygen
8. Group 7A
+1
H20
-2
SO2, HCIO4
-1
HCI
9. Group 6A
-2
PbS,
