Dear Student,


2. 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.
