Different atoms come together to form an element; is not part of Dalton's atomic theory.

Explanation;

-Dalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.

-Dalton’s atomic theory also stated that all compounds were composed of combinations of these atoms in defined ratios.

-Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.
