but it was John Dalton, who lived in Manchester, who proved it more than 2000 years later

Five main points of Dalton's atomic theory1. The atoms of a given element are different from those of any
other element; the atoms of different elements can be distinguished from one another by their respective relative atomic weights.

2. All atoms of a given element are identical. 3. Atoms of one element can combine with atoms of other
elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms.

4. Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.

Dalton proposed an additional "rule of greatest simplicity" that created controversy, since it could not be independently confirmed.

Dalton proposed an additional "rule of greatest simplicity" that created controversy, since it could not be independently confirmed. When atoms combine in only one ratio, "..it must be presumed to be a binary one, unless some cause appear to the contrary".
