The postulates of Dalton’s atomic theory are as follows:
▶All matter is made up of very tiny particles. These particles are called atoms.
▶An atom cannot be divided further i.e., atoms are indivisible.
▶Atoms can neither be created nor destroyed in a chemical reaction.
▶All atoms of an element are identical in all respects, including the mass, chemical properties, etc.
▶Atoms of different elements have different masses and chemical properties.
▶Atoms of different elements combine in small whole number ratios to form compounds.
In a given compound, the relative number and types of atoms are constant.
