Question

explain dalton atomic theory.........

Answer 1

Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought. 1) All matter is made of atoms. Atoms are indivisible and indestructible. 3) Compounds are formed by a combination of two or more different kinds of atoms.

Answer 2

Dalton → John Dalton

He used to fundamental laws of chemical combination that are the law of conservation of mass and law of constant proportion as the basis of his atomic theory.

Conclusion of Dalton's atomic theory : 

Atom is the smallest particle of an element which cannot be further divided and that retains all the characteristic properties of that element.

Some assumption and postulates of Dalton's theory are: 

• An atom cannot be further divided into still smaller particles.

• Atom can neither be created nor be destroyed in the chemical process.

• The atom of one element are different from those of any other elements.

• Atoms of different elements make combine in simple whole number ratio to form compound atoms of a new substance.

• All forms of matter are made up of very small discrete particles called atoms.
