Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te Columbium (tohu "Cb") te ingoa i whakawhiwhia e Hatchett i tana kitenga o te konganuku i te tau 1801. Ko te ingoa e whakaatu ana i te momo tauira o te ore i ahu mai i Amerika (Columbia). I whakamahia tonu tenei ingoa i roto i nga niupepa Amerika - ko te pepa whakamutunga i whakaputaina e te American Chemical Society me te columbium i roto i tana taitara mai i te 1953 - i te wa e whakamahia ana te niobium i Uropi. Hei whakamutu i tenei raruraru, i whiriwhiria te ingoa niobium mo te waahanga 41 i te 15th Conference of the Union of Chemistry i Amsterdam i te 1949. I muri mai i te tau i whakaaetia ai tenei ingoa e te International Union of Pure and Applied Chemistry (IUPAC) i muri i nga tau 100 o te tautohetohe, ahakoa te tuatahi o te ingoa columbium. He momo whakataunga tenei; i whakaaetia e te IUPAC te tungsten hei utu mo te wolfram hei whakaute i te whakamahinga o Amerika ki te Raki; me te niobium hei utu mo te columbium hei whakaute i te whakamahinga o Europi. Ahakoa he maha nga hapori matū o US me nga whakahaere a te kawanatanga e whakamahi ana i te ingoa IUPAC mana, ko etahi o nga tohunga whakarewa me nga hapori whakarewa kei te whakamahi tonu i te ingoa taketake o Amerika, "columbium".  Pātai: He aha te tohu o IUPAC?
