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.
1. 2400 years after Democritus and Leukippus John Dalton postulated that all the matter is formed from indestructible atoms.
2. All atoms of a chemical element are identical (this affirmation is not valid today because isotopes were discovered).
3. Atoms of different elements are different.
4. Chemical reactions are a problem of a new arrangement of atoms.
5. The ratio between atoms in a compound is constant and is an integer (this is not valid today because a great number of nonstoichiometric compounds were discovered).
well by proving that polyatomic ions are the center of an atom therefor using the Pythagorean theorem he has proved that all atoms are a linear equation in the universe
john dalton didnt find the atom democrites did... john dalton was reading and found the word atomos in a journal and decided he would change the name to atom meaning undivisible.
The first person to develop the first model of the atom in 1803 was John Dalton.

John Montgomery Dalton
The atom was discorvered by john dalton in the early 1800's

Actually there are 4 scientists that contributed. The 4 scientists who contributed to current knowledge of the atom are John Dalton, William Crookes, J.J. Thomson, and Ernest Rutherford.
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
