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.

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.
