The element gallium was discovered four years after the publication of Mendeleev's table, and its properties matched up remarkably well with eka-aluminum, fitting into the table exactly where he had predicted.
WebWhen Russian Dmitri Mendeleev produced the periodic table, he grouped elements with similar properties under each other. He left gaps for elements yet to be discovered. Mendeleev predicted the existence of gallium in 1871, which he called eka-aluminium because this undiscovered element would sit under aluminium in the periodic table. … WebScandium, Gallium, and Germanium are the three elements predicted by Mendeleev from the gaps in his periodic table and were known as eka-boron, eka – aluminium and eka-silicon. 12.
