∙ 16y agoThe chemical composition of the Earth (by mass) is:
34.6% Iron
29.5% Oxygen
15.2% Silicon
12.7% Magnesium
2.4% Nickel
1.9% Sulfur
http://seds.lpl.Arizona.edu/nineplanets/nineplanets/earth.html
The mass of the Earth is 5.97e24 kg = 5.97e27 g
Therefore the earth contains
2.07e27g Iron
1.76e27g Oxygen
9.1e26g Silicon
7.6e26g Magnesium
1.4e26g Nickel
1.1e26g Sulfur
The molar masses of these elements are:
55.9g Iron
16.0g Oxygen
28.1g Silicon
24.3g Magnesium
58.7g Nickel
32.1g Sulfur
Therefore the number of moles of each of these elements is:
3.7e25 Iron
1.10e26 Oxygen
3.2e25 Silicon
3.1e25 Magnesium
2e24 Nickel
3e24 Sulfur
for a total of 2.15e26 moles. Multiply by Avogadro's number to get number of atoms = 1.3e50 or so.
(what about the earth's atmoshere?)

∙ 13y agothere are 2 billion atoms in a cm. and there are about 24901.55 miles around earth( if your question is how many atoms AROUND EARTH listen up) and there
is 185318.4 cm. in one mile and that times 24901.55 = 4614715403.52 and that
times 2000000000 (2 billion) =4614715403520000000 and that is how many atoms around earth P.S. if you have any complaints a 2nd grade boy wrote this( it's true!
It is estimated that there are approximately 1.33 x 10^50 atoms on Earth, with the majority of these being hydrogen atoms followed by helium and oxygen atoms.

Does a penny have more atoms than earth does people?
Yes, most definitely, a penny has many more atoms than the Earth does people.A pre-1982 penny contains about 28,000,000,000,000,000,000,000 copper atoms. Or, 2.8 x 1022atoms.There are about 6 billion people on the planet.
If a mole of atoms were spread uniformly over the surface of the Earth how many atoms would there be per square meter?
There are approximately 6 x 10^23 atoms in a mole. The surface area of the Earth is about 5 x 10^14 square meters. So, if a mole of atoms were spread uniformly on the Earth's surface, there would be around 1.2 x 10^9 atoms per square meter.
Which element is alkaline earth element with the least massive atoms?
Beryllium is the alkaline earth element with the least massive atoms.
A smaple of silver with the same mass as the earth would contain how many atoms of silver and how many moles of silver?
A silver sample with the same mass as the Earth (5.972 × 10^24 kg) would contain about 1.96 × 10^50 atoms of silver. This amount of silver corresponds to approximately 3.25 × 10^25 moles.
Is everything on earth made of different types of atoms?
Yes, everything on Earth is made up of atoms. Atoms are the basic building blocks of matter and combine in different ways to form various substances, such as elements, compounds, and mixtures.
How many different kinds of atoms occur naturally on earth and why?
i think 94 kinds of atoms occur to earth
Is an atom part of earth's crust?
Some atoms are part of Earth's crust. Many, many more are not.
How many atoms are Earth made of?
THE EARTH IS AN ADOM DUMBY HEAD!!!!!1!!!1
How would the earth would be like if there was no atoms?
There wouldn't be an earth if there were no atoms.
How many different kinds of atom occur naturally on earth?
94 kinds of atoms occur naturally on earth
Do Atoms affect Earth?
You might say that, considering that the Earth and everything on it are composed of atoms.
What the earth be like if we didn't have atoms?
If we didn't have atoms, the Earth and everything around us wouldn't exist. Atoms are the building blocks of matter, forming everything in the universe, including Earth and all living organisms. Without atoms, there would be no physical structures or substances as we know them.
Is every thing on earth made of atoms?
Atoms exist throughout the universe. the most common atom in the universe is hydrogen. Helium is the second most common found in the universe, and oxygen is the third.
How you got on Earth?
You got to earth by atoms or mater.
Where are atoms at?
In everything on earth
