Dalton's atomic theory suggested that atom was indivisible and indestructible.But the discovery of two fundamental particles i.e electrons and protons inside the atom led to the failure of this aspect of Dalton's atomic theory.Many scientists proved that an atom can be further subdivided into protons, neutrons and electrons.

Limitations of Dalton’s atomic theory
i) Atoms of the same or different types have a strong tendency to combine together to form a new ‘group of atoms’.
ii) With the discovery of sub-atomic particles, e.g., electrons, neutrons and protons, the atom can no longer be considered indivisible.
iii) Discovery of isotopes indicated that all atoms of the same element are not perfectly identical. At least, they differ in their masses. Atoms of the same element having different masses are called isotopes.
in simple u can write it as :-
Dalton’s atomic theory could not explain why certain substances, all containing atoms of the same element, should differ in their properties. For example, charcoal, graphite and diamond all are made up of only Can-atoms, but still their properties are quite different.
