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.
they are not identical. Dalton's model was wrong.
Democratus. (with an a) Dalton came up with the first model.
an atomic model explained several observations.
dalton created a solid sphere model. He belived that the atom was one single sphere, and that diffrent elements were made of diffrent types of atoms.
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.

Dalton's theory was based on the principal that the atoms of different elements that could be distinguished by differences in their weights. In 1803, at the Royal Institution He stated this theory.
Dalton described atoms as solid spheres. Thomson discovered the the atom also contained negatively charged particles called electrons distributed in such a way that the atom had no charge.
