How did the periodic table help scientists between its development in the nineteenth century and 1925, when the last of the naturally occurring elements was identified?
It allowed scientists to predict the existence and properties of undiscovered elements.
It helped scientists to create new synthetic elements before 1925.
It provided a way to measure atomic mass with perfect accuracy.
It enabled scientists to discover all elements through chemical reactions alone.
