It is malleable and highly resistant to common acids and to ...

Niobium was discovered in 1801 by Charles Hatchett. Initially, it was named Columbium (with symbol Cb) after Columbia; a state of United States. Later, due to confusion, it was considered another element, known as tantalum, and in 1846, German Chemist Heinrich Rose proposed that it was indeed a novel element and named it Niobium.

History. Named after Tantalos, a Greek a mythological character, father of Niobe.Discovered in 1802 by Ekeberg, but many chemists thought niobium and tantalum were identical elements until Rowe in 1844, and Marignac, in 1866, showed that niobic and tantalic acids were two different acids. The early investigators only isolated the impure metal. The first relatively pure …

Niobium and tantalum are transition metals almost always paired together in nature. These "twins" are difficult to separate because of their shared physical and chemical properties. In 1801, English chemist Charles Hatchett uncovered an unknown element in a mineral sample of columbite; John Winthrop found the sample in a Massachusetts mine and sent it to the British …
