What was one idea Dalton taught about atom?
All atoms of one type were identical in mass and properties. (Apex 2021)
What single measurable characteristic of atoms did Dalton base his conclusions on?
John Dalton based his conclusions on the measurable characteristic of atomic mass. He proposed that each element consists of unique atoms with specific masses, which could be used to distinguish one element from another. Dalton's atomic theory was grounded in the idea that chemical reactions involve the rearrangement of these distinct atoms, with their mass being a key factor in understanding chemical compounds and reactions.
Who invented the atomic mass unit?
The concept of the atomic mass unit was established by chemist John Dalton in the early 1800s. Dalton introduced the idea of using a standard unit to represent the mass of atoms relative to each other.
What year did john Dalton comes up with the idea that each type of matter is made up of only one kind of atom?
John Dalton proposed his atomic theory in 1803, which included the idea that each type of matter is composed of one kind of atom. His work laid the foundation for modern chemistry by suggesting that atoms of different elements have distinct properties. Dalton's theory was instrumental in advancing the understanding of chemical composition and reactions.

Who believed elements have their own atom?
Dalton, who got the idea from Democritis. Dalton turned this idea into a scientific theory which was All elements are composed of indivisible particles called atoms, Atoms of all elements are different from one another, Atoms of elements can mix together in whole number ratios to form compunds, and Chemical reactions occur as a result of when atoms are separated, joined, or rearranged.
When Dalton's theory is it possible to convert atoms of the one element into atoms of another?
No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.
What are the reasons why Dalton's atomic is not accepted these days?
One part of Dalton's atomic theory that is disregarded is the idea that all atoms in an element are uniform. The type of element is determined by the number of protons, and as such the number of neutrons can fluctuate. As well, Dalton's theory claimed that atoms could not be divided, but they are made of protons, neutrons, and electrons, and can be split apart into these particles.

Which of Dalton's statements about the atom was proven false by j.j Thompson?
One of Dalton's statements that was proven false by J.J. Thomson was the idea that atoms are indivisible and cannot be further divided. Thomson's discovery of the electron showed that atoms are made up of smaller particles, leading to the development of the plum pudding model of the atom.
Who invented the atomic mass unit?
The concept of the atomic mass unit was established by chemist John Dalton in the early 1800s. Dalton introduced the idea of using a standard unit to represent the mass of atoms relative to each other.
According to Dalton how do the atoms from one sample of the element carbon compare to the atoms of another sample of carbon?
They are identical.
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).

What was one main point of Dalton's atomic theory?
Atoms are made up of the smallest form of matter
