What four elements make up 96 percent of the human body?
The four elements that make up 96 percent of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are found in abundance in biological molecules such as water, proteins, carbohydrates, fats, and nucleic acids, which are essential for human life and function.
Which element is most abundant within the human?
Carbon is the most abundant element in the human body. Hydrogen, nitrogen, oxygen, phosphorus and sulfur are next in abundance.
What is the human body mostly made of a carbon oxygen nitrogen and hydrogen b oxygen calcium carbon and hydrogen c hydrogen iron nitrogen and oxygen?
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.
What is the most common molecule in the human body is made of what element?
Oxygen and Hydrogen
What five elements comprise 99.5 percent of the human body?
Nothing. But the closest is water, which makes up about 60%.
What is the rank the four major elements of human body?
The four major elements which together make up 96% of our body mass are carbon, oxygen, nitrogen and hydrogen. The ranking is based on the mass of a 70kg adult: Oxygen - 64.5% of body mass / 43kg out of 70kg Carbon - 18% / 16kg Hydrogen - 10% / 7kg Nitrogen - 3% / 1.8kg
What is the most common element of human body?
By molar amount, hydrogen and oxygen are the most common elements; carbon is the third. By mass, oxygen is the most common, and carbon is the second (with hydrogen being third by mass). By mass, oxygen is the most abundant, and phosphorus is the least, carbon the 2nd, hydrogen, 3rd. By atoms, hydrogen is most abundant, and phosphorus the least, oxygen 2nd, carbon 3rd.
What element is found in the human body?
there are lots of elements in the human body; they are Oxygen, Carbon, Hydrogen, nitrogen, calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium and iron.
What element is most abundant in the earths crust atmosphere and oceans?
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
Is the human body an example of an element?
No, the human body is not an element. The human body is made up of many different elements such as carbon, oxygen, hydrogen, and nitrogen, among others. An element is a pure substance that cannot be broken down into simpler substances by chemical means.
What 4 elements account for more than 95 percent of the human body?
Oxygen, carbon, hydrogen, and nitrogen account for more than 95% of the human body's mass. These elements are essential for building molecules such as proteins, carbohydrates, fats, and nucleic acids, which make up our cells and tissues.
What do most compounds in the human body contain?
carbon, oxygen, hydrogen, and nitrogen
