WebFeb 24, 2024 · Carbon, the basic unit for organic molecules, comes in second. 96.2% of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen, and nitrogen. Oxygen (O) - 65% - Oxygen together with hydrogen form water, which is the primary solvent found in the body and is used to regulate temperature and osmotic pressure. WebMay 18, 2024 · On the periodic table, the element oxygen is shown by the letter O. However, the oxygen present in the atmosphere is shown by the letter O2. The logic here is that O is an oxygen atom. But the atoms live in pairs to make O2 oxygen gas. So, O atoms are just O, and oxygen gas means O2. Still, most of the time people just say “oxygen”.
