Founded a method for measuring atomic mass

Arranged elements in order of increasing atomic mass

Observed that properties were arranged periodically

Was able to predict the existence of elements based on gaps in his table

Found that elements varied by the number of protons in the nucleus

Arranged elements based on atomic number

States that the physical and chemical properties of the elements are functions of their atomic number

A repeating/predictable pattern of properties of atoms as a function of their position on the periodic table

Periodicity is a result of...
