[34], Pure germanium is known to spontaneously extrude very long screw dislocations, referred to as germanium whiskers. Being directly below silicon in the periodic table, germanium has quite similar chemistry and early studies of phytoplankton that make up their structural skeletons ('tests') of biogenic silica (e.g., diatoms), showed that they take up germanium along . [90], Certain compounds of germanium have low toxicity to mammals, but have toxic effects against certain bacteria.

The catalyst is a medium pore germanium zeolite, a germanium aluminophosphate (AIPO) or a germanium silicoaluminophosphate (SAPO). He initially considered the new element to be eka-antimony, but was soon convinced that it was instead eka-silicon. It is one of the elements, whose properties Mendeleev predicted. If you are not sure if your structure is correct, do a formal charge check. We go out of our way to complete jobs on time and in a courteous and friendly manner.
