Laura asked the Naked Scientists:
   
How many atoms does each element of the periodic table have?

What do you think?

Thankyou RD that tells you everything(you could need to begin to answer the question)

When counting atoms...
Avagadro's number gives you the number of atoms in one mole of any substance.

6.0221415 × 1023

You look up in the periodic table the atomic mass (number at the bottom of the block), and that many grams has avagadro's number of atoms.
http://en.wikipedia.org/wiki/Periodic_table_%28large_version%29

So,

1.079 grams of hydrogen has 6.0221415 × 1023 atoms.
4.0026 grams of helium has 6.0221415 × 1023 atoms.
6.941 grams of Lithium has 6.0221415 × 1023 atoms.

etc.

Some of the synthetic elements at the bottom of the periodic table are very unstable (dotted boxes around them).  For some, only a few atoms have been created, and often last for less than a second.

Looking at the question isn't really is asking, looking just at hydrogen. How many hydrogen atoms are there in the universe?

Wyibit, those answers from RD and Clifford are quite informative. Some of the exploration should be left to the asker I think. We're not here to force-feed people, unless it's our own 'pet theories' of course, ahem. But not here, I believe Laura will do well with what she learned :)

I never suggested that there anwers were not, I even said thankyou, as they helped me. My question was just that a question, we are here do discuss right this is a discussion forum.

I might be a bit off the mark here but isn't the answer ONE?  If they had more then one type of Atom then they would not be an element and would be a compound?

Good show Airthumbs! The same thing crossed my mind, but I was afraid to wade in  :)

A lump of copper is made of zillions of atoms, but it's still copper and has just one spot in the periodic table.

"A chemical compound is a pure chemical substance consisting of two or more different chemical elements".

Things like ozone mess up that definition.

I know, but a definition have to be given. I don't know a better one, but maybe there are. What do you think?
