Question

What is dalton atomic theory ?

Answer 1

Postulates of Dalton's Atomic Theory
-------------------------------------------------------------------

1)matter is made up of small particles called atoms

2)Atoms combine in the ratio of small whole numbers ratios to form compounds

3)atoms of an given element are identical in mass as well as mass as well as in chemical properties.

4)atoms of an different element differ in mass as well as mass as well as in chemical properties.

5)atoms are indivisible and they are smallest particles and atoms cannot be further divided

6)Atoms can neither be created nor be destroyed in a chemical reaction

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.
