Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Columbium (chiratidzo "Cb") raiva zita rakatanga kupiwa naHatchett paakawana simbi yacho muna 1801. Zita racho rairatidza kuti rudzi rwomuenzaniso rwezvinonhuwira rwakabva kuAmerica (Columbia). Iri zita rakaramba richishandiswa mumagazini okuAmerica - pepa rokupedzisira rakabudiswa neAmerican Chemical Society rine columbium mumusoro waro rakabva muna 1953 - nepo niobium yaishandiswa muEurope. Kugumisa nyonganiso iyi, zita rokuti niobium rakasarudzwa nokuda kwechinhu 41 paMusangano wechi15 weUnion of Chemistry muAmsterdam muna 1949. Gore rakatevera zita iri rakagamuchirwa zviri pamutemo neInternational Union of Pure and Applied Chemistry (IUPAC) pashure pemakore 100 enharo, pasinei nokuti zita rokuti columbium rakanga riri pamberi. Ikoku kwakanga kuri kubvumirana kwemarudzi; IUPAC yakagamuchira tungsten panzvimbo pe wolfram mukuremekedza kushandiswa kweNorth America; uye niobium panzvimbo pe columbium mukuremekedza kushandiswa kweEurope. Nepo masangano akawanda emakemikari eU.S. nemasangano ehurumende anowanzoshandisa zita repamutemo reIUPAC, vamwe vanogadzira simbi nemasangano esimbi vachiri kushandisa zita rekutanga reAmerica, "columbium".  Mubvunzo: IUPAC inomiririra chii?
