Q:
Are there any pictures of Dalton’s atomic model? I can’t seem to find any and am having a hard time drawing one. Thanks!

A:
Dalton's atomic theory proposed that there were atoms that were indivisible particles. The reason why you had a hard time finding a drawing is because he did not even think about the structure of the atoms. I found a site that might help you out.

A:
John Dalton, 1766 1844, was an English chemist and physicist.  He is considered one of the foremost originators of the modern theory of atomic structure of compounds.  He postulated that atoms were the indivisible smallest parts of the various elements, such as hydrogen, oxygen, iron, etc, and that compound substances such as water and methane were made out of simple combinations of these various atoms.   He made many experiments showing the plausibility of this hypothesis.    See:  http://en.wikipedia.org/wiki/John_Dalton
