Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.

His theory contained five main propositions:-

• All matter is comprised of tiny, definite particles called atoms.
• Atoms are indivisible and indestructible.
• All atoms of a particular element share identical properties, including weight.
• Atoms of different elements contain different mass.
• Atoms of different elements combine in fixed whole-number ratios when forming compounds.
