Write the postulates of Dalton's Atomic theory.

Explanation

The main postulates of Dalton's atomic theory are:
1) Matter consists of indivisible particles called atoms.
2) Atoms are neither created nor destroyed in a chemical reaction , but atoms will reorganize.
3) All the atoms of a given element have identical mass and chemical properties.
4) Atoms of different elements have different masses and chemical properties.
5) Compounds are formed when atoms of different elements combine in simple whole number ratios i.e., chemical charge is the union or separation of atoms as a whole number.
