Taking the top 5 elements in the body, their % of the body's mass (assumed to be 70 kg) we can calculate the number of moles of each in the body:
Element: Percent by mass: Grans per body: Moles per body for 70 kg
Oxygen: 65: 45000: 3000
Carbon:18: 12600: 1050
Hydrogen: 10: 7000: 7000
Nitrogen: 3: 2100: 175
Calcium: 1.5: 1950: 54
Giving a total number of moles as 11280 = 1x104 (more or less)
And knowing the number of atoms per mole (Avogadro's number) = 6.03 x1023
Number of atoms in a body is around 6.03 x1027
Atoms are the basis of physical matter, and elements are made of atoms. DNA is a very complex molecule made of many atoms. It is like the difference between concrete blocks and an apartment building.
how should i know! :[
Only three.
volume
Everything is made out of atoms.
21 different kinds of atoms
Be sure, we are not atoms; but as all the universe, we are made from many atoms !!
The chemical formula of water is H2O. It implies it is made of three atoms.
All are made of atoms.
many different atoms
All are made of atoms.
cells are made of many particles called atoms right ? so what are atoms made of? semi cells ..... semicells are made of many tinier particle of science
Simple Answer: A LOT!
yes

Everything is made of atoms so, yes, you ARE made of atoms.
Many scientists believe that everything is made of atoms.
