Explanation:

A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates:

(1) Elements consist of indivisible small particles (atoms).

(2) All atoms of the same element are identical; different elements have different types of atom.

(3) Atoms can neither be created nor destroyed.

Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass. Compounds are produced through different whole-number combinations of atoms.

the limitations of dalton's atomic theory

The main drawbacks of Dalton's Atomic Theory are: (i) It could explain the laws of chemical combination by mass but failed to explain the law of gaseous volumes. (ii) It could not explain why atoms of different elements have different masses, sizes, valencies, etc.
