Give one major drawback of Dalton’s atomic theory.
Some common drawbacks of Dalton's atomic theory are :
1. According to the theory, an atom is the smallest indivisible particle of an element. However, it is now known that atoms can further be subdivided into elementary particles like electrons, protons, and neutrons.
2. According to the theory, atoms of the same element are identical in all respects, having the same size, shape and structure, and especially mass. But, now we know that atoms of the same element can have slightly different masses. Such atoms are called isotopes.
3. It says that atoms of different elements have different properties and different masses. However, different elements do exist whose atoms have the same mass. Such atoms are called isobars.
