The main points of Dalton's atomic theory, as it eventually developed, are: Elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass and other properties; atoms of different elements differ in size, mass and other properties.
According to Dalton's atomic theory :
- All matter is made up of atoms which are indivisible and indestructible.
- Atoms of the same element have the same property and same mass.
- Compounds are made up of atoms of different elements.
- Atoms are rearranged in a chemical reaction.
