$answer$

Postulates of Dalton's atomic theory:

=>All matter consists of indivisible particles called atoms.

=>Atoms of the same elements are similar in shape and mass but differ from the atoms of other elements.

=>Atoms cannot be created or destroyed.

=>Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

=>The atom is the smallest unit of matter that can take part in a chemical reaction
