The 4 main postulates of Dalton's Atomic Theory
What are 1. All matter is made of indivisible and indestructible atoms. 2. Atoms of the same element are identical, and atoms of different elements are different. 3. Compounds are formed by combining elements. 4. Matter cannot be created or destroyed. A chemical reaction is the rearrangement of atoms.
