According to chem.libretexts.org, Dalton's Atomic Theory has multiple postulates: 1. All matter consists of indivisible particles called atoms. 2. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. 3. Atoms cannot be created or destroyed. 4. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. 5. Atoms of same element can combine in more than one ratio to form two or more compounds. 6. The atom is the smallest unit of matter that can take part in a chemical reaction. The Law of Definite Proportions states that a chemical compound will always contain its elements in fixed ratio by mass. Given this information, it can be said that postulate four can prove the Law of Definite Proportions since it mentions that fixed ratios form compound atoms.
