-Compounds are made by a combination of two or more different atoms.

-A chemical reaction is a rearrangement of atoms.

2. Many unexplained chemical phenomenon were quickly explained by the theory.

3. Dalton also created the atomic theory because he thought it would help others of understanding of why water absorbs different gasses in different proportions.

4. Dalton based his theory of partial pressures on the idea that only like atoms in a mixture of gasses repel one another, but different atoms appear to react toward one another.

5. According to "Antoine.frostburg.edu" the atomic theory was not accepted for many years because Dalton included an additional claim.
