Why isn't hydrogen listed as the most common element in the human body, rather than oxygen?
Flexi Says:
Human body made of about 60 to 70 percent of water or H2O. Even though there are twice more atoms of hydrogen in water than oxygen, but by mass oxygen is 16 times heavier than oxygen therefore elements oxygen (O) and hydrogen (H) are the first and third elements, respectively, in the human body.
