According to Dalton's atomic theory
All matter, weather an element, a compound or a mixture is composed of small particles called atoms . The postulates of this this theory may be follows:-
All matter, weather an element, a compound or a mixture is composed of small particles called atoms . The postulates of this this theory may be follows:-
- All matter is made up of very tiny particles called atoms, which participate in chemical reactions.
- Atoms are indivisible particles, which cannot be created or destroyed in chemical reaction.
- Atoms of a given element are identical in mass and chemical properties.
- Atoms of different element have different masses and chemical properties.
- Atoms combine in the ratio of small whole numbers to form compounds.
- The relative number and kinds of atoms are constant in a given compound.
