This scientist attempted to explain the existence of the ether by proposing two elements smaller than hydrogen.
This scientist attempted to explain the existence of the ether by proposing two elements smaller than hydrogen. This man theorized elements which he called eka-boron and eka-silicon based on the chemical properties of boron and silicon. He predicted the properties of the undiscovered elements of gallium and scandium based upon their theorized atomic weights, which were arranged in a diagram later organized by atomic number. For 10 points, name this Russian chemist who developed an early version of the periodic table.
