Dear student,

The five postulates of Dalton’s Atomic Theory can be stated as:
  • All matter around us consists of indivisible particles called atoms.
  • Atoms of the same element 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.
  • Atoms of same element can combine in more than one ratio to form two or more compounds.

1) All matter, whether an element, compound or a mixture is made up os extremely small particles called atoms.
2) Atoms of the same element are identical in all respects, I.E. In shape, size, mass and properties. 
3) Atoms of different elements have different sizes and masses. 
4) Atoms of the same or different elements combine together to form molecules or compounds. 
5) The number and kind of atoms in a given compound is always fixed. 
6) An atom can neither be created nor be destroyed. 
7) Atom is the smallest particle that takes place in a chemical reaction.
