The incorrect postulates of the Dalton's atomic theory are:
(A) Atoms of different elements differ in mass.
(B) Matter consists of divisible atoms.
(C) Compounds are formed when atoms of different element combine in a fixed ratio.
(D) All the atoms of given element have different properties including mass.
(E) Chemical reactions involve reorganisation of atoms.
Choose the correct answer from the options given below:
(B), (D) only
(B) is incorrect because Dalton said atoms are indivisible, but subatomic particles exist.
(D) is wrong as Dalton assumed all atoms of an element are identical, but isotopes disprove this.
(E) is actually correct, as chemical reactions involve reorganization of atoms.
Hence, correct incorrect statements are only (B) and (D).
