What are the top 5 elements in the human 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. All 11 are necessary for life.
What are the 5 essential elements of life?
If we consider the chain of human genes, account must also be taken of the element carbon. In this mode, the four elements of life become the five elements of life: Oxygen, hydrogen, nitrogen, phosphorus and carbon.
What four elements make up 96 of the human body?
Body elements Carbon, hydrogen, oxygen and nitrogen make up 96% of our body’s mass.
Which is not one of the four most abundant elements that make up the human body?
The four most common elements are oxygen, carbon, hydrogen and nitrogen. Along with calcium and phosphorus, they make up 99% of the mass of living organisms. Sulphur is the element that is not one of the four most common elements.
What are the 10 most abundant elements in the human body?
Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are the most abundant elements found in the human body, followed by potassium, sulfur, sodium, chlorine, and magnesium.
Which is the most abundant element in the body?
Oxygen 65.0% Carbon 18.5% Hydrogen 9.5% Nitrogen 3.2% Calcium 1.5%
What are the four elements of the human body?
The four elements are oxygen, hydrogen, carbon, nitrogen. Before you start thinking we should float away with all the oxygen, hydrogen, and nitrogen atoms, remember that the oxygen molecules are mainly part of the water in our body (H2O). In fact, over half of the human body is made up of water (50-70%).
Which is the second most important element in the human body?
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.
What is the most abundent element in the universe?
The most abundant element in the universe is hydrogen, which makes up about 3/4 of all matter! Helium makes up most of the remaining 25%. Oxygen is the third most abundant element in the universe.
What five elements make up most of the human body?

What 4 elements is 96% of the human body made of?
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.
What are the basic elements of the human body?
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.
