Mendeleev used the elements above his empty gaps to calculate and predict the exact physical and chemical properties of the missing elements: →right arrow Discovered 4 years later as Gallium "Eka-boron" →right arrow Discovered 10 years later as Scandium "Eka-silicon" →right arrow Discovered 17 years later as Germanium Other scientists forced elements into rigid grids even

When these elements were finally discovered with properties almost identical to his predictions, the scientific community universally accepted his periodic system.
