What 3 elements did Mendeleev predict? Soon, Mendeleev was predicting the properties of three elements – gallium, scandium and germanium – that had not then been discovered. earache meansWebbHowever, the properties predicted by D.I Mendeleev for eka-aluminium, eka-boron and eka-silicon coincided with those of gallium, scandium, and germanium. Mendeleev had determined the main features of these elements long before they were discovered in nature. Is not this fact a striking evidence of the periodic system’s power of prediction? earache mayo clinicWebbThe messy road to periodic chemistry.
