oxidation numbers

Postby Kyle Rex 1K » Thu Feb 20, 2020 9:44 pm

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

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

if oxidation number decreases, it means it was reduced by gaining electrons

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

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
