what is the chemical composition of the human body listed by elements and amounts of each element?

Question

If this question has been asked 8 times before, why is DriverRob listing Chlorine as a trace?

what is the cause of discrepancy when some list carbon at 61.7 and another list carbon at 18%?

Answer 1

Oxygen (65%)
Carbon (18%)
Hydrogen (10%)
Nitrogen (3%)
Calcium (1.5%)
Phosphorus (1.0%)
Potassium (0.35%)
Sulfur (0.25%)
Sodium (0.15%)
Magnesium (0.05%)
Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%)
Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts)

It's nearly always quicker to find the best answer to a factual question by searching the web, not Yahoo answers.

Answer 2

Carbon... 61.7
Nitrogen.. 11.0
Oxygen.. 9.3
Hydrogen... 5.7
Calcium.. 5.0
Phosphorus..3.3
Potassium.. 1.3
Sulfur.. 1.0
Chlorine.. 0.7
Sodium.. 0.7
Magnesium..0.3

Trace amounts of B, F Si, V, Cr, Mn, Fe, Co, Cu, Zn, Se, Mo, Sn, I.
There are some arguments as to the importance of other trace elements. If
you happen to know a farmer with cows or cattle, take a look at the
nutritional contents of "calf pellets" and you can see what they think a
calf needs in its diet to be healthy...we are just another mammal.


The human body consists of ~7 x 1027 atoms arranged in a highly aperiodic physical structure. Although 41 chemical elements are commonly found in the body's construction CHON comprises 99% of its atoms. Fully 87% of human body atoms are either hydrogen or oxygen.






Hydrogen H 4.22 x 1027 rubidium Rb 2.2 x 1021
