Question

What chemical element is most abundant in the human body?

Answer 1

Chemical elements:

1. The four elements of the human body that make up the largest percentage of our body weight (96.2%) are oxygen, hydrogen, carbon, and nitrogen.
2. Oxygen is the most abundant element in the human body, accounting for about 65% of a person's mass.
3. Each water molecule is made up of two hydrogen atoms bonded to one oxygen atom, but the mass of each oxygen atom is much larger than the combined mass of the hydrogen.
