What elements make up humans?

Answer 1

The elements that make up the body are:

Carbon

Hydrogen

Oxygen

Phosphorous

Potassium

Iodine

Nitrogen

Sodium

Calcium

Iron

Magnesium

along with traces of copper, selenium, cobalt

Answer 2

Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

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)

Answer 3

Humans are primarily composed of oxygen, carbon, hydrogen, and nitrogen. These elements combine to form molecules such as proteins, carbohydrates, and fats, which in turn make up the tissues and organs in the human body. Other essential elements include calcium, phosphorus, potassium, sulfur, sodium, and magnesium.
