What are the four parts of Dalton's atomic theory?

1. Each element is composed of extremely small particles called atoms.

2. All atoms of an element are identical, but they are different from the atoms of different elements.

3. Atoms of one element cannot be changed into atoms of a different element by chemical reactions. Atoms are neither created nor destroyed in chemical reactions.

4. Compounds are formed when atoms of more than one element combine. A given compound always has the same relative number and kinds of atoms.
