state the various postulates of Dalton's atomic theory of matter

Postulates of Dalton's atomic theory are as follows:

• All matter 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 ratio to form compound atoms.

• Atoms of same element can combine in more than one ratio to form two or more compounds.

• Atoms are the smallest unit of matter that can take part in a chemical reaction.
