Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
the Greek Philosophers did not test their theory.
Atoms cannot be divided into smaller particles.
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
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.
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.
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.
True. Dalton's atomic theory, proposed in the early 19th century, was based on careful measurements of chemical reactions and extensive research into the properties of elements. His theory laid the groundwork for modern atomic theory and helped advance the understanding of the composition of matter.
One statement from Dalton's atomic theory that is no longer considered true is that atoms of a given element are identical in mass and properties. We now know that atoms of the same element can have different masses due to the existence of isotopes, which are atoms with the same number of protons but different numbers of neutrons. Additionally, advancements in quantum mechanics and the understanding of atomic structure have revealed that atomic properties can vary significantly, challenging the idea of uniformity among atoms of the same element.
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.
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.
