Which of Dalton's postulates can be disproved today?
Dalton's postulate that atoms are indivisible has been disproved with the discovery of subatomic particles like protons, neutrons, and electrons. Additionally, his postulate that all atoms of the same element are identical has been disproved with the existence of isotopes.
Was John Dalton's statement that atoms are indivisible correct?
John Dalton's statement that atoms are indivisible was not entirely correct. While atoms were once thought to be the smallest indivisible units of matter, advancements in atomic theory revealed that atoms are composed of subatomic particles, such as protons, neutrons, and electrons. Additionally, atoms can undergo processes like nuclear fission, which further demonstrates that they can be divided under certain conditions. Thus, while Dalton's ideas laid the foundation for modern chemistry, the concept of indivisibility has since been revised.
What are john Dalton Discoveries?
John Dalton is best known for his pioneering work in the development of modern atomic theory. His discoveries included the concept that all matter is made up of indivisible particles called atoms, that each element is made of unique atoms, and that chemical reactions involve rearrangement of these atoms. Dalton's work laid the foundation for future advancements in the field of chemistry.
Which of daltons 4 ideas were proven incorrect?
Dalton's idea that atoms are indivisible particles has been proven incorrect, as atoms are made up of protons, neutrons, and electrons. Additionally, his idea that all atoms of the same element are identical in mass has been disproven due to the existence of isotopes.
What would have happend in the gold foil experiment if daltons theory had been correct?
If Dalton's theory had been correct in the gold foil experiment, all the alpha particles would have passed straight through the gold foil with little to no deflection. Dalton's theory proposed that atoms were indivisible and uniform in structure, so there would have been no interactions with the densely packed positive nucleus within the gold atoms.
Which of Dalton's postulates can be disproved today?
Dalton's postulate that atoms are indivisible has been disproved with the discovery of subatomic particles like protons, neutrons, and electrons. Additionally, his postulate that all atoms of the same element are identical has been disproved with the existence of isotopes.
Why is John Dalton's atomic theory still mentioned in science?
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
What is one of Dalton's theories that has been disproved?
Dalton theorized that an atom was a tiny solid sphere. Today we know that atoms are not solid, in fact are mostly open space.
The atomic theory proposed by Dalton has been?
The atomic theory proposed by Dalton has been widely accepted and forms the foundation of modern chemistry. It states that all matter is composed of small, indivisible particles called atoms, which combine in simple whole number ratios to form compounds. Dalton's theory also introduced the idea that atoms of different elements have different properties.
Which of Dalton's ideas on atomic theory have been applied to current theory?
Dalton's idea that elements are composed of indivisible atoms, that atoms of the same element are identical, and that atoms combine in simple whole number ratios in chemical reactions have been incorporated into current atomic theory. However, his hypothesis that atoms are indivisible has been proven wrong by the discovery of subatomic particles like protons, neutrons, and electrons.
Did John Dalton conclude all atoms of a single element have the same mass?
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
Which of Dalton's POINT PROVEN FALSE?
One of Dalton's key points that has been proven false is the idea that atoms of a given element are identical in mass and properties. In reality, atoms of the same element can have different masses due to the existence of isotopes, which contain varying numbers of neutrons. Additionally, the notion that atoms cannot be subdivided has been disproven, as atoms can be broken down into subatomic particles (protons, neutrons, and electrons).

How did Dalton's Atomic Theory effect culture and living conditions?
Daltons atomic theory changed the way people looked at everything in science,Dalton proved that matter is not able to be broken down past a specific point, (the atom) and that all matter is made up of atoms and now medicine and science have been able to be better, building materials stronger,ect, ect
What do scientists no longer believe about daltons ideas?
Scientists no longer believe in Dalton's idea that atoms are indivisible and are the smallest particles of matter because further research has shown that atoms can be broken down into even smaller subatomic particles like protons, neutrons, and electrons. Additionally, Dalton's notion that all atoms of the same element are identical has been revised with the discovery of isotopes, which are atoms of the same element with different numbers of neutrons.
