Answer 2

1) Dalton told that atoms are indivisible particles. But it can be further divided into proton, neutron and electron.
2) According to Dalton, atoms of the same element have identical masses and chemical properties. However, they can vary in case of isotopes.
3) Dalton told that atoms of different elements have different masses and        chemical properties. But, this has been proved wrong in the case of isobars.
4) According to Dalton, atoms combine in the ratio of small whole numbers to form compounds. This is not observed in complex compounds such as sugars.
