    Niobium (pronounced /naɪˈoʊbiəm/), or columbium (/kəˈlʌmbiəm/) is a chemical element that has the symbol Nb and atomic number 41. A rare, soft, gray, ductile transition metal, niobium is found in pyrochlore and columbite. It was first discovered in the latter mineral and so was initially named columbium; now that mineral is also called "niobite".
