Which four elements are the most important to life?
The four most important elements in cells are carbon, hydrogen, oxygen and nitrogen..
Why is hydrogen so important?
The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons etc.

What are the 7 elements of life?
The seven Elements are Nature, Water, Fire, Earth, Light, Darkness, and Spirit.
What is the most dangerous element?
PlutoniumPlutonium A History of the World’s Most Dangerous Element.
What are the 3 most important elements?
Carbon, hydrogen and oxygen combine to form proteins, carbohydrates (which is a combination of carbon with water) and lipids, all compounds essential to life. Oxygen makes up approximately 26 percent of the human body.

What are the six elements of life?
The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulphur and phosphorus.
What is the most unknown element?
astatineDiscovered in 1940, astatine (element number 85) leaves a “curious void” in the periodic table of the elements: Its properties in solid or liquid, or condensed form, are simply unknown, report researchers.
What elements do we need to survive?
Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What element makes up most of the human body?
Nitrogen – 2.4kg The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
Why are the elements important?
Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body. … The human body functions as a result of a large number of chemical reactions involving compounds of all of these elements.

What is the least known element?
Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth’s crust, occurring only as the decay product of various heavier elements. All of astatine’s isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours.
