Aspiring chemists need to be able to count electrons. Without this ability, your days as a chemist would be numbered. In this tutorial, you will learn how to count electrons to assign formal charges and oxidation states. Both forms of "electron bookkeeping" are important concepts to understand for organic reactions.
