What are the 4 abundant elements?
The four most abundant elements in living cells are b) Carbon, oxygen, hydrogen, nitrogen.
Which element is most abundant in the human body?
Oxygen is the most common element in the human body, comprising approximately 65.0% of body mass. Most of the oxygen present is found in the form of water.
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 four most abundant elements in the human body quizlet?
The four most abundant elements are Oxygen, Carbon, Hydrogen, and Nitrogen which comprise 65%, 18.5%, 9.5%, and 3.2% of the human body, respectively.

Which metal is found in human body?
The remaining two and a half percent of your body are largely metals − sodium, potassium, magnesium, calcium, manganese, iron, cobalt copper, zinc, and molybdenum − and despite their relatively low total mass, these elements are just as important as the first 97.5%.
Which one is not one of the four most abundant elements in life?
Complete Answer: 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 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.
What are the 4 elements that make up human body weight?
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. 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).
