What are the 5 most important elements on earth?
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.

What is the less common element on Earth?
Astatine is the rarest naturally occurring element on Earth, with less than 1 gram present in Earth’s crust at any one time. Not only is very little Astatine found in nature, it is very difficult to produce, even in its most stable form Astatine-210.
What is the origin of all elements on Earth?
An atom is a particle of an element. All elements (over 109 are known) originated from stars long ago. The theoretical model of the atom, developed about 200 years ago, is fundamental to understanding chemistry. Atoms are depicted as microscopic spheres, composed of 3 types of subatomic particles, known as protons, electrons, and neutrons.
What do elements form Earth?
Except for hydrogen and some helium created in the Big Bang, all of the stuff we, and the Earth around us, are made of, was generated in stars, through sustained fusion or in supernova explosions. The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium.
