Q

Daltons Postulates

A
  1. All matter consist of atoms (Mass conservation law)
  2. Atoms of one element cant be converted into atoms of another element (Mass conservation law)
  3. Atoms of an element are identical in mass & other properties & are different from atoms of any other elements
  4. Compounds results from the chemical combination of a specific ratio of atoms of different elements (Definite composition law)
