Question

Which postulate of Dalton could not explain about isotope? Write the postulate. ​

Answer 1

Explanation:

Dalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.

Dalton’s atomic theory also stated that all compounds were composed of combinations of these atoms in defined ratios.

Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.

Answer 2

Answer:

Dalton also stated that atoms all similar in all aspects, but this fails to explain the existence of isotopes, which are atoms of the same elements with different masses. Thirdly, Dalton also stated that atoms of different elements combine in simple whole number ratios to form compounds.N
