Pure germanium is known to spontaneously extrude very long screw dislocations, referred to as germanium whiskers. The growth of these whiskers is one of the primary reasons for the failure of older diodes and transistors made from germanium, as, depending on what they eventually touch, they may lead to an electrical short.

To place germanium into the periodic table, Mendeleev suggested that it might be ekacadmium, an element he had predicted earlier. In contrast, Lothar Meyer favored an identification of germanium with ekasilicon, a different predicted element. Winkler isolated more of the pure material, and eventually obtained enough to measure some of its ...
For example, germanium was called eka-silicon until its discovery in 1886, and rhenium was called dvi-manganese before its discovery in 1926. The eka-prefix was used by other theorists, and not only in Mendeleev's own predictions. Before the discovery, francium was referred to as eka-caesium, and astatine as eka-iodine.
Germanium comes from the Latin word Germania, the Latin name for Germany, which is the country where germanium was discovered. Stannum comes from the Latin word stannum , meaning "tin", from or related to Celtic staen .
Thomas E. Murray (October 21, 1860 – July 21, 1929) was an American inventor and businessman who developed electric power plants for New York City as well as many electrical devices which influenced life around the world, including the dimmer switch and screw-in fuse.
Template documentation This page uses the meta infobox {{ Infobox isotopes (meta) }} for the element isotopes infobox. This infobox contains the table of § Main isotopes , and the § Standard atomic weight .
For example, this is why the template writes "(at 0 °C)". For this, you may want to experiment with parameter input too - or propose improvements. All this can vary across the values (data rows). So depending on the row and the specific value, additional formattings may be added by the template (e.g., a newline <br/>) Central data values
