The periodic table of elements below is color coded to show the elements found in the human body. The Top Four Elements Found in the Human Body. Of the elements found in the human body, four of them make up the largest percentage of our body weight (96.2%). The four elements are oxygen, hydrogen, carbon, nitrogen. Before you start thinking we should float away with all the oxygen, hydrogen, and nitrogen atoms, remember that the oxgen molecules are mainly part of the water in our body (H2O). In fact, over half of the human body is made up of water (50-70%).
