John dalton atomic theory
John Dalton’s atomic theory given the primary basis of chemistry of an atom but today atomic theory grows up by discovering the electron cloud model.
All the chemical reactions in chemistry clearly explained by this model.
- Matter made of atoms is indivisible and indestructible.
- All the atoms of a given element are identical mass and properties.
- Compounds formed by the combination of two or more same or different kinds of atoms.
- A chemical reaction is a rearrangement of atoms.
But Dalton’s model of indivisibility of atom discarded by the discovery of various elementary particles like proton, neutrons, and electrons.
