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

Answer 1

Oxygen is element that is found in the highest percentage by weight in the human body. The body consists of 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium, 1% phosphorus, and other elements with increments of less than 1%.

Answer 2

Hydrogen accounts for 63% of our atoms, but oxygen accounts for 65% of our mass.

Answer:

There are 60 types of elements normally detectable in the human body with two dozen known to be either essential or beneficial. Three, however, H,C, and O,

make up the majority of our atoms.

Long Answer:

Hydrogen represents 63% of the atoms in our body but only 10% of our mass.

Oxygen is almost 2/3 rds (65%) of our mass but only 12% of our atoms.

Carbon is 1/8th (12%) of the atoms and 18% of the mass.

Together, H+C+O, account for 63+24+12=99% of the atoms and 65+18+10=93% of our mass.

One has to add in nitrogen + calcium + phosphorus + potassium + sulfur (=3%+1.4%+1.1%+.25%+.25%) to get 7% more and account for 99% of our mass.

Answer 3

Oxygen is about 63% of the human body by mass.

Oxygen is in many biological molecules, but most of it is in water.

Numerically, hydrogen atoms represent 63% of all atoms in the human body. That varies too, because many of the hydrogen are abound up in water and water content varies.

Water by itself can be 63% of the mass of a human. (It varies with age, gender, muscle and and body fat, but is 55-65% for adults and more for children.)

As one can see, many things are 63% of the human body.

Answer 4

Oxygen.


Oxygen is the most abundant element in the earth's crust and in the body. The body's 43 kilograms of oxygen is found mostly as a component of water, which makes up 70% of total body weight. Oxygen is also an integral component of all proteins, nucleic acids (DNA and RNA), carbohydrates, and fats.

Well, this amount of oxygen obviously might vary according to the weight of every individual, age, gender, etc. However, in terms of percentage, oxygen keeps on being the most abundant element.

Answer 5

water - H2O----next user---- -Wrong! Water is a compond! It's Oxygen! Plus, It's H2O. Wow....

Answer 6

By mass, the element that makes up the greatest percentage is oxygen at around 65%.

Answer 7

The most important element in the human body is oxygen with a percentage of 65 % (not 95 % !).

Answer 8

Oxygen!
