All the eka-elements were later discovered: eka-aluminum (1875) was called gallium; eka-boron (1879), scandium; and eka-silicon (1886), germanium. Mendeleev also predicted the existence of analogues of manganese (future Tc and Re), and tellurium (Po), iodine (At), cesium (Fr), barium (Ra), and tantalum (Pa).
