Postulates:

1. All matter comprises of inseparable particles called iotas.

2. Atoms of a similar component are comparative fit as a fiddle and mass, however contrast from the iotas of different components.

3. Atoms can't be made or annihilated.

4. Atoms of various components may consolidate with each other in a settled, straightforward, entire number proportions to shape compound molecules.

5. Atoms of same component can join in more than one proportion to shape at least two mixes.

6. The molecule is the littlest unit of matter that can partake in a concoction response.

The indissoluble nature of a particle was demonstrated wrong: an iota can be additionally subdivided into protons, neutrons and electrons. However an iota is the littlest molecule that participates in synthetic responses.

• According to Dalton, the iotas of same component are comparative in all regards. Be that as it may, iotas of a few components differ in their masses and densities. These molecules of various masses are called isotopes. For instance, chlorine has two isotopes with mass numbers 35 and 37.

• Dalton additionally asserted that particles of various components are distinctive in all regards. This has been demonstrated wrong in specific cases: argon and calcium molecules each have a nuclear mass of 40 amu. These molecules are known as isobars.
