Dalton’s atomic theory can be explained as follows:

1)      Matter  is made up of atoms. Atoms are indivisible and indestructible.

2)      All atoms of a certain element are identical in mass and properties.

3)      Compounds are formed by a combination of two or more different kinds of atoms.

4)      A  chemical reaction is a rearrangement of atoms.


In short we can say that,

Dalton’s atomic theory states that matter consists of indivisible particles called atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules).
