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.
Dalton's atomic theory incorrectly stated that atoms of the same element are identical, which we now know is not true due to the existence of isotopes. Additionally, Dalton stated that atoms cannot be divided, when in fact they can be split into subatomic particles like protons, neutrons, and electrons.
John Dalton thought that atoms were indivisible, that all matter is composed of tiny indivisible atoms, and he thought that atoms in a given element are identical.

How can an stm help improve daltons theory?
An STM (scanning tunneling microscope) can help improve Dalton's atomic theory by providing visual evidence of individual atoms and their arrangements on surfaces. This experimental data can offer insights into the precise structure and behavior of atoms, supporting or refining Dalton's ideas based on empirical observation. Additionally, STM allows for the direct observation of atomic interactions and bonding, which can lead to a deeper understanding of atomic behavior beyond what Dalton's theory originally proposed.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
The weight in daltons of one atom of an element is?
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
If all four postulates of Daltons atomic theory are correct what would change about the boxes on the periodic table and Why?
If all four postulates of Dalton's atomic theory were correct, the boxes on the periodic table would not change. Dalton's theory helped establish the concept of elements as composed of atoms, leading to the organization of elements on the periodic table based on their atomic number and properties. The periodic table would still be structured according to the number of protons in the nucleus of each element's atom.
How many daltons does one molecule of water have?
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
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.
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.
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.
In what way does Dalton's theory differ from modern atomic theory?
he was wrong

What theory has passed many tests and has not been proven wrong?
Evolution, Atomic Theory
How was Thomsons atomic theory different from Rutherfords atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
