What is not one of the most abundant elements in the body?

Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.

What are the 6 most abundant elements in the human body?

The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulphur and phosphorus.

What elements are abundant in the human body?

The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.

Which element is most abundant in human body?

Oxygen
Oxygen definitively holds first place, making up 65% to 67% of the human body by weight, Townsend said. That’s because our bodies are mostly water — around 50% to 60% — so most of the oxygen is the “O” in H2O.

What is the second most abundant element in the human body?

Carbon
Carbon is the second most abundant element in the human body, accounting for 18% of body weight.

Which is the most abundant element in our body?

oxygen
By mass, oxygen is the most abundant element in the human body. If you think about it, this makes sense, since most of the body consists of water or H2O. Oxygen accounts for 61-65% of the mass of the human body.

What is the 2nd most abundant element in the human body?

carbon
All living organisms contain carbon, which forms the basis for all of the organic molecules in the body. Carbon is the second most abundant element in the human body, accounting for 18% of body weight.
