A few years after this prediction, a French guy named Paul Emile Lecoq de Boisbaudran discovered a new element in ore samples and named it gallium after Gaul, the historical name for France.

Gallium is one step away from aluminum on the periodic table.

Not only did Mendeleev completely nail gallium, he predicted other elements that were unknown at the time: scandium, germanium, rhenium.

The pioneers of microelectronics tried many strategies to supplant vacuum tubes, and they delivered a host of semiconductors and chip designs: germanium, silicon, aluminum, gallium arsenide, PNP, NPN, CMOS, and so on.

Other precious metals that are teased from the Earth, including indium, gallium, palladium, and ruthenium, are being discarded in much the same way as other electronic waste (e-waste).
