Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Nemhaka yokuti kashoma kuwanika muzvikamu zvikuru, germanium yakawanwa gare gare munhau yekemisitiri. Germanium inenge iri panhamba yechishanu maererano nokuwanda kwezvinhu zviri mudenga repasi. Muna 1869, Dmitri Mendeleev akafanotaura kuvapo kwayo nezvimwe zvinhu zvayo kubva panzvimbo yayo iri patafura yake yenguva nenguva, uye akadana chinhu chacho kuti ekasilicon. Anodokusvika makumi maviri amakore gare gare, muna 1886, Clemens Winkler akawana chinhu chitsva pamwe chete nesirivha nesarufa, mune chicherwa chisingawanzowaniki chinonzi argyrodite. Kunyange zvazvo chinhu chitsva chacho chakanga chakafanana nearsenic neantimony nechitarisiko chayo, mwero wokubatanidza zvinhu zvacho wakawirirana nezvakanga zvafanotaurwa naMendeleev nezveimwe hama yesirilicon. Winkler akatumidza chinhu chacho zita renyika yake, Germany. Nhasi, germanium inonyanyocherwa zvikurukuru mu sphalerite (mhangura huru yezinc), kunyange zvazvo germanium ichidzorerwawo mune zvokutengeserana mu sirivha, mutobvu, uye mhangura.  Mubvunzo: Mendeleev akafanotaura kuvapo kweekasilicon mugore ripi?
