What element has Nb?

niobium (Nb), chemical element, refractory metal of Group 5 (Vb) of the periodic table, used in alloys, tools and dies, and superconductive magnets. Niobium is closely associated with tantalum in ores and in properties.

What is Nb in chemistry?

Niobium is a chemical element with symbol Nb and atomic number 41. Classified as a transition metal, Niobium is a solid at room temperature.

What niobium is used for?

Niobium is used in alloys including stainless steel. It improves the strength of the alloys, particularly at low temperatures. Alloys containing niobium are used in jet engines and rockets, beams and girders for buildings and oil rigs, and oil and gas pipelines.

Why was it assigned such a name niobium?

Niobium is named for the Greek goddess of tears, Niobe, who was the daughter of king Tantalus, according to the Royal Society of Chemistry, due to the element’s similarities to tantalum (named for the king).

Who discovered NB?
