The 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?)

94 kinds of atoms occur naturally on earth


No. Earth is a planet. It is made of uncountably many atoms.



There wouldn't be an earth if there were no atoms.


there 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!


i dont know... probally 1000 ?


As francium is the rarest type of atoms in the world, there is approximately only 20 francium atoms left on Earth.


You might say that, considering that the Earth and everything on it are composed of atoms.


There wouldn't be an earth or anything at all if we didn't have atoms


You got to earth by atoms or mater.


In everything on earth


No. All mater on earth is made of atoms. Atoms have mass.


A mole of any substance contains 6.02x1023 atoms. The surface of the earth is about 510x106 km2. This surface area is the same as 5.10x1014 m2. Therefore each square meter would have (6.02x1023 atoms)/(5.10x1014 m2) atoms/m2. This reduces to 1.18x109 atoms/m2


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.


Yes. All matter on earth is made of atoms.


Atoms are the fundamental building blocks of matter on the Earth.


The main reason is that earth is made by atoms. Everything in earth are atoms. Solids have atoms close together, water have atoms that are loose and gas have atoms that are so loose that it just goes to places rapidly. Earth is a solid with water, which is a liquid, and air, which is a gas.


EVerything on earth consists of atoms. and all atoms consist of smaller atoms, but scientists have only gotten so far in the chain.


Yes. Atoms are matter. All the matter you encounter on Earth is made of atoms.


2. Nitrogen in the atmosphere here on Earth is considered diatomic.



No atoms did not create earth. Everything is made of atoms and the big bang create the universe which made a nebula and created the sun and the asteroids built up to form a large asteroid and made its own gravity which made the earth circular. That created earth.


Yes. All materials you will find on earth contain atoms.


Their abundance on earth is in the ratio 7 : 12


There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.
