John Dalton (1766-1844)

Atoms are small particles that cannot be created, divided or destroyed.

Atoms can combine toform compounds.

He thought water was 1 hydrogen and 1 oxygen.

H O


Dalton’s Hypothesis

IF all atoms of a given element are identical and atoms of differing elements are different from one

another, THEN atoms of one element can combine with the atoms of other

elements to form chemical compounds.
