What parts of Dalton’s atomic theory no longer agree with the current picture of the atom? Provide an answer using 3 – 4 sentences in your own words.

Answer 1

1.Atoms actually are divisible. (e.g. by nuclear reactions)
2.All atoms of a given element don't have to have identical mass and properties. (e.g. we know 3 isotopes of hydrogen, which have different number of neutrons thus different mass)
