340 Unit 3: Chemical Interactions About 25 common elements make up living things. Close to 100 elements occur naturally.Of these,25 are found in living things.As you can see in the pie graph at the left,about 97 percent of your bodyÃs mass consists of just four major elementsÃ oxygen,carbon,hydrogen,and nitrogen. Major Elements The six most common elements in living things are carbon,hydrogen,oxygen,nitrogen,phosphorus,and sulfur.Atoms of these elements combine and form
