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.
What else can I help you with?
What part of Daltons atomic theory was then proven to be incorrect?
Two principles not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
What experiment did daltons use for his atomic theory?
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
Was Dalton's hypothesis that atoms are indivisible and all atoms of an element are identical?
That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.
What are five points of Daltons atomic theory and witch where proven wrong?
Dalton's atomic theory includes the following five points: 1) All matter is composed of indivisible atoms; 2) Atoms of the same element are identical in mass and properties; 3) Compounds are formed by the combination of different kinds of atoms; 4) A chemical reaction involves the rearrangement of atoms; 5) Atoms cannot be created or destroyed in a chemical reaction. However, points one and two were proven wrong; atoms are not indivisible (they can be split into subatomic particles) and isotopes show that atoms of the same element can have different masses.
What part of Daltons atomic theory was then proven to be incorrect?
Two principles not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
What part of daltons atomic theory was proved incorrect?
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.
How does Daltons atomic theory explain the law of definite proportions?

How did daltons atomic theory lead to the different model scientists have today?
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
Why scientists accepted daltons atomic theory but not the idea of an atom proposed by the Greek philosopher?
the Greek Philosophers did not test their theory.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Can a scientific theory be incorrect?
"Can a theory be proven incorrect?" absolutely, even after it has been successfully proven a "good scientific theory" (proven as in experimented, documented, tested ect...... )The theory itself can be retested and then also be proven to be incorrect. Such as subtle changes in the environment of which the study was tested can alter the results to be give a true or false outcome. Thus, in my opinion much of the reasoning behind the statement nothing in the World is absolutely 100%.
Is the atomic theory changeable?
Any theory is subject to change until proven
What experiment did daltons use for his atomic theory?
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
What theory has passed many tests and has not been proven wrong?
Evolution, Atomic Theory
Which part of daltons atomic theory are known to be incorrect?
Dalton's atomic theory stated that atoms of a given element are identical in all respects, which we now know is incorrect as atoms can exist as isotopes with different numbers of neutrons. Additionally, atoms were thought to be indivisible, but we now know they can be broken down into subatomic particles like protons, neutrons, and electrons.
Why was daltons model accepted?
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
