How did john Dalton help add knowledge of the atom?

Answer 1

By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.

Answer 2

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.

Answer 3

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).

Answer 4

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
