Explanation:

Dalton's atomic theory had some inaccuracies. Isotopes showed that atoms of the same element can have different masses, disproving that all atoms of the same element are exactly alike. Also, the discovery of sub - atomic particles like electrons, protons, and neutrons showed that atoms are divisible.

Answer:

All atoms of the same element are exactly alike.
Atoms are indivisible and indestructible particles.
