Question

Give one major drawback of Dalton's atomic theory of matter. Dalton's atomic theory says that atoms are indivisible. Is this statement still valid? Give reasons for your answer.

Answer 1

The drawback of Dalton's atomic theory:
According to the theory, an atom is the smallest indivisible particle of an atom. However, it is now known that atoms can further be subdivided into elementary particles like electrons, protons, and neutrons.


"Dalton's atomic theory says that atoms are indivisible" this statement is not valid now as it is found that an atom has a complex structure and is composed of subatomic particles such as electrons, protons, and neutrons.
