A large fraction of the chemical elements that occur naturally on the earth’s surface are
essential to the structure and metabolism of living things
. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm.
Why are elements important to life?
1. 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.

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. 25 elements are known to be essential to life.
What is the most important element for human life?
The most important structural element, and the reason we are known as
carbon-
based life forms. About 12 per cent of your body’s atoms are carbon. The hydrogen atoms in your body were formed in the Big Bang.
What elements are most important?

What’s the most useful element?
Life demands a huge variety of molecules, with chains and rings and branches and cages—tricks that iron rarely attempts. And so we are left with
carbon
, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.
What elements do we use everyday?
The most important elements that we use in everyday life include
carbon, hydrogen, oxygen
, with smaller amounts of things like chlorine, sulfur, calcium, iron, phosphorus,nitrogen, sodium, and potassium. Apart from these, other elements include magnesium, zinc, neon, and helium are also in our daily existence.
Which elements have no uses?
A few elements have no current uses, such as
protactinium and berkelium
. The short-lived, man-made elements starting with einsteinium have no uses at the moment either, as they don’t stick around long enough for scientists to experiment on them.
What is element in simple words?
element. [ ĕl′ə-mənt ]
A substance that cannot be broken down into simpler substances by chemical means
. An element is composed of atoms that have the same atomic number, that is, each atom has the same number of protons in its nucleus as all other atoms of that element.

Oxygen, hydrogen, nitrogen, phosphorus and carbon
.
How many elements are in the human body?
The human body is approximately 99% comprised of just
six
elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium. All of these 11 elements are essential elements.
