The oxidation number of an atom in a compound or in its pure state is its charge when it becomes an ion. This is the value that is the main concern in a redox reaction. It is the one monitored because the corresponding change in this value will mean that the chemical species undergoes...
In general, trends in average Mn oxidation state before ~600 Ma are less certain due to larger uncertainties caused by the smaller number of preserved deposits. An exception to this uniformly low oxidation state is an increase from +2 to greater than +2.5 in the average oxidation state of...
