What is the most plentiful in the body?

What is the most plentiful in the body?

Oxygen
Oxygen. By mass, oxygen is the most abundant element in the human body. If you think about it, this makes sense, since most of the body consists of water or H2O. Oxygen accounts for 61-65% of the mass of the human body.

What are the most abundant substances in the body?

Water is one of the most essential elements in the body; in fact, it is the most abundant substance in the human body and is a major component of every cell.

What is the human body made of mostly?

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.

What is the most common substance in the world?

A: Oxygen, which composes about 49.5% of the total mass of the Earth’s crust, waters and atmosphere, according to the textbook “Modern Chemistry.” Silicon is second at 28%. Aluminum is a distant third, at only 8%.

What are the top 10 most abundant element in the human body?

Answer: 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.

What is the most abundant element in the atmosphere?

Nitrogen
