Answer:
1. It fails to explain why atoms of different kinds differ in mass and valency.
2. The discovery of isotopes and isobars showed that atoms of same elements can have different atomic masses and atoms of different kinds may have same atomic masses.
3.The discovery of subatomic particles like electrons, protons and neutrons lead to the idea that atom was no longer an indivisible particle of matter.
