oxidation numbers
when an oxidation number decreases, is it reduced? or is it oxidized because does the oxidation number lowering correlate to a loss of electrons?

Re: oxidation numbers
a more negative number indicates a greater number of electrons (higher negativity), however with oxidation/reduction, you have to look at each element in the molecule's oxidation number to figure out if it is being reduced or oxidized because a more negative molecule doesn't necessarily mean its been reduced

Re: oxidation numbers
But generally I'm pretty sure that an element is oxidized when the oxidation number is increased, and is reduced when the oxidation number decreases

Re: oxidation numbers
A decrease in number means a decrease in charge, which signifies reduction because it gains an electron and goes down in charge. vice versa for increase
