What is the most abundant chemical in the human body?
Oxygen
Oxygen is the most abundant element in the human body accounting for approximately 65% of a person’s mass….Elements in the Human Body.
| Element | Percent by Mass |
|---|---|
| Oxygen | 65 |
| Carbon | 18 |
| Hydrogen | 10 |
| Nitrogen | 3 |
What is the abundant substance in the body?
Oxygen. Oxygen is the most abundant element in the human body. It makes up 65 percent of the total weight of a person.
How many chemicals are in our body?
Some 60 chemical elements are found in the body, but what all of them are doing there is still unknown. 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.
How many chemicals are in the human body?
What are the top 5 most abundant elements in the universe?
- 1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
- 2.) Helium. About 28% is helium, with 25% formed in the Big Bang and 3% from stellar fusion.
- 3.) Oxygen.
- 4.) Carbon.
- 5.) Neon.
- 6.) Nitrogen.
- 7.) Magnesium.
- 8.) Silicon.
What is the most abundant substance in our universe?
Hydrogen
Hydrogen is the most abundant element in the Universe; helium is second….Universe.
| Z | Element | Mass fraction (ppm) |
|---|---|---|
| 1 | Hydrogen | 739,000 |
| 2 | Helium | 240,000 |
| 8 | Oxygen | 10,400 |

Which is the most abundant element in the human body?
C is carbon, H is hydrogen, N is nitrogen, O is oxygen, P is phosphorus, and S is sulfur. While the acronym is a good way to remember the identities of the elements, it doesn’t reflect their abundance. Oxygen is the most abundant element in the human body accounting for approximately 65% of a person’s mass.
How many chemical elements make up the human body?
Elements in the Human Body . Six elements account for 99% of the mass of the human body. The acronym CHNOPS may be used to help remember the six key chemical elements that are used in biological molecules. C is carbon, H is hydrogen, N is nitrogen, O is oxygen, P is phosphorus, and S is sulfur.
Which is the most abundant compound in a cell?
Water and minerals are inorganic compounds. Organic compounds include fat, protein, carbohydrates, and nucleic acids. Water: Water is the most abundant chemical compound in living human cells, accounting for 65 percent to 90 percent of each cell.
Why is carbon the second most abundant element in the body?
In addition to being a component of water, oxygen is essential for cellular respiration. Carbon is contained in all organic compounds, which is why carbon is the second most abundant element in the body, accounting for about 18% of body mass. Carbon is found in proteins, carbohydrates, lipids, and nucleic acids.
