what is the percentage of elements in a human body?
478540
It is thus no wonder that 99% of the atoms in the human body come from six elements: Hydrogen (62.9%), oxygen (almost 24%), carbon (nearly 12%), nitrogen (nearly 0.6%), calcium (0.24%) and phosphorus (0.14%).

Let's see – it is estimated that an adult human has about 7 billion billion billion atoms (that's a 7 followed by 27 zeros!!). Your hands take up about one half of a percent of your total body weight – so one hand takes up about a quarter of a percent, or 0.025th of your total body weight.

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.
1073642
The four basic elements of life are: Oxygen, hydrogen, nitrogen and phosphorus. These four elements are found in abundance in both the human body and in animals.
1068218
Eight elements make up 98% of the Earth's crust: oxygen, silicon, aluminium, iron, magnesium, calcium, sodium and potassium. The composition of minerals formed by igneous processes is directly controlled by the chemistry of the parent body.

Keep in mind that body composition includes muscle, fat, bones, organs, tendons and ligaments. ... THey say that typically, a woman holds about 30% of her bodyweight in skeletal muscle, and men have about 40%. So if you're a lean individual, 50% isn't that far off.
79426
Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements.

Elemental iron is the total amount of iron in the supplement available for absorption by your body. Each type of iron has a different percent of elemental iron. For instance: Carbonyl has 100% elemental iron.

For men, a healthy fat percentage is between 10% and 20% and for women, between 18% and 28%. Muscle mass percentage: as the term suggests, this number indicates how much of your total weight is muscle mass. This is calculated by dividing the weight of your muscle mass by your total body weight.

Most of the human body is water, with an average of roughly 60%. The amount of water in the body changes slightly with age, sex, and hydration levels. While the average percentage of water in a person's body is around 60%, the percentage can vary from roughly 45–75%.
1140472
Of the elements found in the human body, four of them make up the largest percentage of our body weight (96.2%). The four elements are oxygen, hydrogen, carbon, nitrogen.
339836
The number of atoms per human cell is only a rough estimate because cells come in different sizes. Scientists estimate the average cell contains 100 trillion atoms. The number of atoms per cell is about the same as the number of cells in the body.
636412
More than half your body is not human. More than half of your body is not human, say scientists. Human cells make up only 43% of the body's total cell count. The rest are microscopic colonists.
338308
As you can see in the pie graph at the left, about 97 percent of your body's mass consists of just four major elements— oxygen, carbon, hydrogen, and nitrogen. The six most common elements in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
436681
The four basic elements of life are: Oxygen, hydrogen, nitrogen and phosphorus. These four elements are found in abundance in both the human body and in animals. There are other elements that compose the human body, but the four we've highlighted participate in all life processes.
1006978
Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body.

But skin isn't all "fleshy" stuff. As an organ, skin is made up of everything that covers one's body, including the nails and hair . In total, skin accounts for about 16 percent of a person's total body weight. Most adults' skin weighs in at 20 pounds or more.
