What is the contribution of John Dalton in the development of atom?

Answer 1

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

John Dalton's most important theory, developed in 1803, was that matter is composed of atoms of differing weights that combine in simple ratios. Dalton published a book in 1808 listing the atomic weights of a number of known elements relative to the weight of hydrogen. Although not entirely accurate when published, those weights form the basis for the modern periodic tableof the elements. John Dalton has been honored by having his name used as the international Atomic Mass unit, equivalent to 1/12 of the mass of a neutral carbon-12 atom, the dalton.
