What part of daltons theory was modified after the discovery of isotope?
Atoms may not be changed into other atoms.
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
How does Daltons atomic theory explain the law of definite proportions?

How did Bohr reduced mass theory assisted by Urey to discover deuterium?
Bohr's reduced mass theory predicted the existence of isotopes. Urey used this theory to isolate the heavy isotope of hydrogen, deuterium, by separating it from normal hydrogen using fractional distillation. This discovery confirmed the existence of isotopes and provided evidence for the theory of nuclear structure.
How did the discovery of radioactivity contradict Dalton's atomic theory?
radioactivity proves that there are smaller particles in an atom that makes it up, they are proton, neutron, and electron. Dalton's atomic theory clearly states that the atom is the simplest particle. Radioactivity contradicts Dalton's theory since it proves that there are particles which are simpler than the atom.
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.
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.
How did subatomic particles and isotopes affect the atomic theory?
The discovery of subatomic particles like electrons, protons, and neutrons contributed to a better understanding of the structure of atoms. Isotopes, which are atoms of the same element with different numbers of neutrons, helped refine the atomic theory by explaining variations in atomic mass. Together, these discoveries have shaped our modern understanding of atomic structure and behavior.
When was The Discovery of Grounded Theory created?
The Discovery of Grounded Theory was created in 1967.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
What did daltons theory say about protons and electrons?
Nothing,Dolton did not know about Protons,neutrons and electrons
What happened to daltons theory in the late 1800s?
In the late 1800s, Dalton's atomic theory underwent significant revisions due to advancements in scientific understanding. The discovery of subatomic particles, such as electrons by J.J. Thomson in 1897, challenged the notion of indivisible atoms. Additionally, the development of the periodic table and insights into chemical bonding revealed that atoms of the same element could exist in different isotopes, contradicting Dalton's assertion that all atoms of an element are identical. These developments led to a more nuanced understanding of atomic structure and behavior.
