Question

The following are the six most common elements in the human body: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Each of these elements is heavier than hydrogen and helium. Explain how and where these elements formed.

Answer 1

Explanation : It is thus no wonder that 99% of the atoms in the human body come from six elements: Hydrogen (62.9%), oxygen (almost 24%), carbon (nearly 12%), nitrogen (nearly 0.6%), calcium (0.24%) and phosphorus (0.14%). Calcium is on the list as it is essential for our skeleton, which contains 99% of the calcium in our body.
