Given the evidence available at the time (early 1800's) nothing was wrong with Dalton's theory. It accounted for the variations among elements, their relative masses, the observed conservation of mass, and the observations made by earlier scientists about the proportions of elements found in compounds. Dalton did conjecture that atoms somehow stuck together to make compounds, but he couldn't explain how. It was only much later that electrons were discovered, showing that atoms weren't indestructible solid objects, and later still that it was shown that atoms had a specific internal structure, the exact nature of which is still under investigation. None of these discoveries invalidate Dalton's atomic theory -- they expand and enrich it. Dalton's theory did exactly what good scientific theories do -- explain and relate existing evidence, and provide a foundation for further inquiry.

ttha atoms made up pthe smallest forms of matter
If all four postulates of Daltons atomic theory are correct what would change about the boxes on the periodic table and Why?
Are you doing this for a "cumulative take home exam"?
Which part of daltons atomic theory are known to be incorrect?
The idea that atoms are indivisible and indestructible, and the idea that all atoms of the same element have the same mass.
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.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
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.

Did postulate 4 of Daltons atomic theory holds true now?
This postulate is valid today only in some situations.
In what way does Dalton's theory differ from modern atomic theory?
he was wrong
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.
How is the modern atomic theory different from Daltons atomic theory?
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.
