Gained electrons
WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be … WebGenerally, you can find out whether electrons are lost or gained by looking at the number of oxygen and hydrogen bonds. If oxygens are gained, or hydrogens are lost, then it's oxidation. If oxygens are lost or hydrogens are gained, then it's reduction. NADPH loses its bond to hydrogen. It's oxidized.
