Some of you will go to the germanium mines, some to the fishing fleet, some will be apprenticed to various trades.The Status Civilization
In 1875 Lecoq de Boisbandram discovered gallium, which filled one of the gaps; scandium and germanium filled the other two later.
Germanium 64 is not at all stable, and neither is Neodymium 128, but the instability can be corrected by positive beta emission.The Bramble Bush
