• There are a minimum of 32 known radioactive isotopes of niobium. • Heinrich Rose that the tantalum ore included a second element, which he named niobium.• Both names were used until niobium was chosen as the name for this element, in 1949.• Niobium didn't have a commercial use until the 1900s.• Primarily used to mix with other metals.• Niobium mixes produce a special steel for stronger gas pipelines.• Just 0.1%of Niobium improves the structural strength of steel dramatically.

• Reacts with:◦ Fluorine, chlorine, bromine, and iodine• Not toxic• Under most circumstance, niobium is flammable
