*The Elements in the Human Body:-* ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ Most of the human body is made up of water, therefore H2O, with cells consisting of 65-90% water by weight. Hence most of the human body consist of Oxygen by mass. Then the basic unit or building block of organic molecules Carbon ranks the 2nd. * 99% of the mass of the human body is made up of six elements: 1. oxygen 2. carbon 3. hydrogen 4. nitrogen 5. calcium 6. phosphorus. Average value in % of the elements:- ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 1. Oxygen (65%) 2. Carbon (18%) 3. Hydrogen (10%) 4. Nitrogen (3%) 5. Calcium (1.5%) 6. Phosphorus (1.0%) 7. Potassium (0.35%) 8. Sulfur (0.25%) 9. Sodium (0.15%) 10. Magnesium (0.05%) 11. Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%) 12. Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts) *Atif*
