Question

1. state two misconceptions of dalton’s atomic theory.

Explanation:

Dalton's atomic theory had several limitations. One was the belief that atoms are indivisible. Later, sub - atomic particles like electrons, protons, and neutrons were discovered. Another misconception was that all atoms of a given element are identical. Isotopes (atoms of the same element with different masses due to different numbers of neutrons) disprove this.

Answer:

1. Atoms are indivisible (disproven by discovery of sub - atomic particles).
2. All atoms of an element are identical (disproven by isotopes).
