Niobium-Discovery, Properties, And Applications

Niobium is a chemical element with the symbol ‘Nb’ and atomic number 41. It is a transition metal that is commonly used in alloys due to its unique properties. Niobium was first discovered in 1801 by Charles Hatchett, but it was not widely recognized as a distinct element until 1844 when Heinrich Rose discovered that it was different from tantalum. The element is named after Niobe, the daughter of Tantalus in Greek mythology.
