Democritus initial recommended the existence of the atom however it took nearly 2 millennia before the atom was placed on a solid foothold as a basic chemical object by physicist (1766-1844). though 2 centuries recent, Dalton's atomic theory remains valid in trendy chemical thought. From yesteryear, philosophers were nonplussed regarding the character of matter. They were suggesting that every one matter consists of little, discrete, indivisible particles known as atom.In 1808, John Dalton recommend the atomic theory, and with success explained the laws of chemical combination acknowledged at that point. Dalton’s atomic theory is also summarized within the following postulates.
1. All the matter consists of very tiny indivisible component particles known as atoms
2. Atoms of same component area unit all alike.
3. Atoms completely different|of various} parts area unit entirely different, and have completely different properties.
4. Atoms can't be destroyed, created or reworked into atoms of different parts.
5. Atoms mix along in easy number magnitude relation to relinquish compounds.
6. The relative range every kind of atoms area unit constant during a given compound .
Dalton’s atomic theory is that the milestone within the development of contemporary chemistry. Dalton’s original statement has undergoes enlargement, modification, and clarification to an excellent extent. consistent with chemist atoms unite along to from chemical compounds. The quantitative weight relationship during a chemical relation is extremely vital. Modern atomic theory is, of course, a bit a lot of concerned than Dalton's theory however the essence of Dalton's theory remains valid. nowadays we all know that atoms may be destroyed via nuclear reactions however not by chemical reactions. Also, there ar completely different sorts of atoms (differing by their masses) inside a component that ar called "isotopes", however isotopes of a component have a similar chemical properties.
Many up to currently unexplained chemical phenomena were quickly explained by Dalton along side his theory. Dalton's theory quickly became the theoretical foundation in chemistry.
