Answer 1

Gee. Thanks, for your help, guys.

Answer 2

Lol you guys suck!

Answer 3

If anyone reads this question and is wondering the same thing, Dalton's Atomic theory was (in summary ) that
1. All matter is composed of atoms
2. Atoms of any given (PURE ) element are uniform/identical, but different from the atoms in another element.
3. Atoms cannot be subdivided, created, or destroyed.
4. Atoms of different elements combine in whole number ratios, forming chemical compounds.
5. In chemical reactions, atoms are combined, separated, or rearranged.


Now, contrasting the modern Atomic Theory, the changes that were made can be put simply. Dalton was proven wrong in 3 of the 5 statements listed above. The only of Dalton's atomic theory which has not yet been disproven, and still holds true would be that...

1. All matter is composed of atoms.
2. Atoms of any single element differ in properties from that of the atoms in another element.
