Drawbacks of Dalton's Atomic Theory
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions.
What is false about Dalton's theory?
Some parts of Dalton's theory were wrong: atoms are divisible into smaller particles (subatomic particles) atoms of the same element can have different masses (isotopes)
What parts of Dalton's theory are not valid anymore?
Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed.
