Explanation:
The postulates of Dalton's atomic theory are;
- Matter is made up of indivisible particles known as atoms.
- Atoms of same elements have same properties while atoms of different elements have different properties.
- Atoms of different elements combine in fixed ratios to form compounds.
- Atoms are neither created nor destroyed.
- The formation of new products (compounds) results from the rearrangement of existing atoms (reactants).
By comparing the postulates above and those in the questions, we find that only the following postulates are part of the daltons atomic theory;
1. Atoms combine in fixed ratios of whole numbers.
2. Atoms of each element have different properties.
