The Ge-S distance is 2.19 . Identifiers ; CAS Number. . If you are not sure if your structure is correct, do a formal charge check. 90 degrees 109.5 degrees 120 degrees 180 degrees. Because it's located in group 14 of the periodic table, germanium has 4 valence electrons. Click on the molecule's name to see the answer, but first try to do it yourself! You should consult the Lewis structure rules and a periodic table while doing this exercise. arrow_forward. Its name comes from Germania, the Latin name of Germany. See the table below. The germanium is reduced by sodium borohydride to germane (GeH 4 ), stripped from solution by a helium gas stream, and collected in a liquid-nitrogen-cooled trap.
