Oxidation numbers The oxidation number is the charge that an atom appears to have when the electrons are distributed according to certain rules. 1. The oxidation number of Transition Metal Oxidation State Chromium +2, +3, +6 Manganese +2, +3, +4, +6, +7 Iron +2, +3, +6 Copper +1, +2 an uncombined el...
Oxidation numbers The oxidation number is the charge that an atom appears to have when the electrons are distributed according to certain rules. 1. The oxidation number of Transition Metal Oxidation State Chromium +2, +3, +6 Manganese +2, +3, +4, +6, +7 Iron +2, +3, +6 Copper +1, +2 an uncombined element is zero. 2. The sum of oxidation numbers in a molecule is zero. 3. The oxidation number of an ion of an element is the same as its charge. 4. The sum of the oxidation numbers of all atoms in a complex ion equals the charge on that ion. 5. Hydrogen has an oxidation number of +1 when bonded. 6. Oxygen has an oxidation number of -2. Exceptions: In peroxides its oxidation number is -1, When bonded to fluorine, its oxidation number is +2. 7. In compounds Group 1 elements have an oxidation number of +1 & Group 2 elements are +2. 8. Halogens have an oxidation number of -1 when bonded electronegative atom to a less
