Dalton's atomic theory included the idea that matter is composed of indivisible atoms, which are the fundamental building blocks of all substances. It proposed that atoms of a given element are identical in mass and properties, while atoms of different elements differ in these respects. Additionally, Dalton suggested that chemical reactions involve the rearrangement of atoms, rather than their creation or destruction. This theory laid the groundwork for modern chemistry by introducing the concept of atoms as discrete units of matter.

What idea compromised the acceptance of daltons atomic theory work?
One key idea that compromised the acceptance of Dalton's atomic theory was the notion that atoms are indivisible and indestructible. Subsequent discoveries in chemistry and physics, particularly the identification of subatomic particles (such as electrons, protons, and neutrons), demonstrated that atoms are not the smallest units of matter and can indeed be split or transformed in nuclear reactions. This revelation necessitated refinements to Dalton's original theory, leading to a more nuanced understanding of atomic structure and behavior.
What is a component of John Daltons atomic theory?
One key component of John Dalton's atomic theory is the idea that matter is composed of indivisible particles called atoms. Dalton proposed that all atoms of a given element are identical in mass and properties, and that atoms combine in simple whole-number ratios to form compounds. This theory laid the groundwork for modern chemistry by introducing the concept of the atomic nature of matter.
What was benjamen franklin's contribution to the atomic theory?
Benjamin Franklin's contribution to the atomic theory was his proposal that electricity was a fundamental force that could be understood through atomic models. He conducted experiments with electricity and proposed the idea of positive and negative charges, which later contributed to the development of the atomic theory.
Who disagrees with daltons major points of the atomic theory?
One of the main figures who disagreed with John Dalton's atomic theory was J.J. Thomson, who discovered the electron and proposed the "plum pudding" model of the atom, suggesting that atoms are composed of smaller particles and are not indivisible as Dalton proposed. Additionally, later developments in quantum mechanics and the discovery of subatomic particles contradicted Dalton's idea of atoms as solid, indivisible units. These advancements highlighted the complexity of atomic structure, leading to a more nuanced understanding of matter.
What year did Niels Bohr proved his atomic theory?
Niels Bohr published his atomic theory in 1913...which applied Max Planck's quantum theory to Rutherford's idea of a nuclear structure.... adding the idea of electrons traveling in orbitsaround the atom's nucleus.
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.
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.
What main feature of daltons atomic model was abandoned after thomson's discoveries?
The idea that atoms are indivisible.

Is the atomic theory a verb?
"The atomic theory" is a noun, because it is an idea. It neither elicits action, nor does it connect nouns.
Which part of daltons atomic theory are known to be incorrect?
Dalton's atomic theory stated that atoms of a given element are identical in all respects, which we now know is incorrect as atoms can exist as isotopes with different numbers of neutrons. Additionally, atoms were thought to be indivisible, but we now know they can be broken down into subatomic particles like protons, neutrons, and electrons.
What was Lavoisier's contributions to the development of the modern atomic theory?
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
Who is idea led to the atomic theory of matter?
By john Dalton in 1808
Rutherford's atomic theory included which idea?
The structure of an atom is just like the solar system. ==================================== The above answer is incorrect. Rutherford's atomic theory included the idea that Elcectrons float around a nucleus with protons.
What statement from daltons theory no longer true?
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.
What is the relationship between Democritus and Dalton's atomic theory?
Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
