欧博官网What part of Daltons atomic theory was proven
There is no one single individual who can be given complete credit for disproving Dalton's theory. Setting aside that Dalton's theory is still, in part, accepted, the portions of the theory that have been disproved are: All atoms are identical: Since different isotopes of different atoms occur, that is not entirely accurate. Atoms of the same element are all identical in that they contain the same number of protons. We can give credit to Margaret Todd for coining the word "Isotope". Frederick Soddy went on to win the Nobel prize in 1921 for his work on radioactive substances.
Atoms are indivisible and indestructible: Atoms can, of course, be split. Fission and fusion nuclear reactions disprove this part of his theory. If Dalton had been more precise and said that atoms cannot be split by chemical reactions, we could still accept that portion of his theory. Scientists responsible for developing the wave-matter character of the atom are Debroglie, Schrödinger, Heisenberg, Max Planck, Al Einstein and many others...You can't really give full credit to anyone.
