Mendeleev predicted three elements namely Eka- aluminum (which turned out to be Gallium), Eka- boron (which turned out to be Scandium) and Eka- silicon (which turned out to be Germanium).
Though these three elements are very famous, Mendeleev also predicted Eka- manganese (which turned out to be Technetium).
