1 – Oxygen (Approximate Percentage by weight: 46.6%)

Oxygen Abundant Element on earth
Not only part of the Earth’s crust, these elements they are the basic building blocks of pretty much everything around us!
Oxygen is a chemical element with symbol O and atomic number 8.oxygen is the third-most abundant element in the universe,

2 – Silicon (Approximate Percentage by weight: 27.7%)

Silicon Abundant Elements in the earth
Some of these elements are found combined with other elements as compounds (A compound is multiple elements joined together).
Silicon is a chemical element with symbol Si and atomic number 14.

3 – Aluminum (Approximate Percentage by weight: 8.1%)

Aluminum Most Abundant Elements in the Earth

Some of this list are rare and precious, but others are used in everyday things. In fact, you might well have consumed some of them today. Aluminum or aluminum is a chemical element with symbol Al and atomic number 13.

4 – Iron (Approximate Percentage by weight: 5.0%)

Iron Most Abundant Elements in the Earth’s Crust

This is only the top ten elements in the earth’s crust which makes up a very, very tiny percentage of the Earth as a whole. Iron is a chemical element with symbol Fe and atomic number 26. It is a metal in the first transition series.

5 – Calcium (Approximate Percentage by weight: 3.6%)

Calcium Most Abundant Elements in the Earth’s Crust
The Earth’s crust is just 3–44 miles thick and represents less than 1% of the earth’s total volume. Calcium is a chemical element with symbol Ca and atomic number 20. An alkaline earth metal, calcium is a reactive pale yellow metal that forms a dark when exposed to air

6 – Sodium (Approximate Percentage by weight: 2.8%)

Sodium Most Abundant Elements in the Earth’s Crust
There are over 3000 minerals known to be in the Earth crust, which would have made a very long list indeed. Sodium is a chemical element with symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal.

7 – Potassium (Approximate Percentage by weight: 2.6%)

Pottasium Most Abundant Elements in the Earth’s Crust
Talking about weight, this list is percentage-based, but if it was down to a percentage of weight it would be very different indeed. Potassium is a chemical element with symbol K and atomic number 19. It was first isolated from potash, the ashes of plants, from which its name derives.potassium is one of the alkali metals.

8 – Magnesium (Approximate Percentage by weight: 2.1%)

Magnesium Most Abundant Elements in the Earth’s Crust
Each of these elements has a definite chemical composition and structure. Some are much more complicated than others which also makes them heavier as well. Magnesium is a chemical element with symbol Mg and atomic number 12.

9 – Titanium (Approximate Percentage by weight: 0.44%)

Titanium Most Abundant Elements in the Earth’s Crust
All of these minerals in this list are substances that have formed naturally in the Earth. But I suppose it is only a matter of time before a man-made mineral rises up the list.

10 – Hydrogen (Approximate Percentage by weight: 0.14%)

Hydrogen Most Abundant Elements in the Earth’s Crust
These elements are very important to mankind, not just the Earth and its crust. Hydrogen is a chemical element with symbol H and atomic number 1.
