All atoms of one type were identical in mass and properties. (Apex 2021)
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.
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.
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.

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.
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.
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.
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.
They are identical.

The five main points of John Dalton's atomic theory are as followed: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element. · Atoms of one element can combine with atoms of other elements to form compounds. · A given compound always has the same relative numbers of types of atoms. · Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.
