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 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.
What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
Did postulate 4 of Daltons atomic theory holds true now?
No, postulate 4 of Dalton's atomic theory, which stated that atoms of the same element are identical, is not entirely true. We now know that isotopes exist, which are atoms of the same element with different numbers of neutrons. This means that atoms of the same element can have slightly different masses.

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.
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.
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.
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
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 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.
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.
