How do you find the oxidation number of one element?
The oxidation number of an element is generally
Oxidation state is formally the charge on an atom when it donates or accepts electrons. While this is a formal exercise it does have utility in the balancing of redox equations. Because elements have demonstrably not transferred electrons, they are assigned a
The burning of coal and fossil fuels is certainly an example of a redox equation:
For both these redox equations mass and charge are balanced, as they must be. (Are they?)
Add them together to eliminate the electrons:
Both elemental reactants are zerovalent BEFORE electron transfer occurs.
