Niobium Element in Periodic Table | Atomic Number Atomic Mass
Niobium is also known as columbium, is a chemical element and it is a member of group 5 and period 5 in the periodic table. The atomic number of niobium is 41 and it is indicated by symbol is Nb. It is a soft, grey and ductile transition metal. Niobium is the 34th most common element in the Earth’s crust with 20 ppm. Nb can occur in combination with other elements in minerals and cannot found free in nature. 93Nb is the one stable isotope of niobium.
Uses Of Niobium Element:
- Niobium is used with iron and other elements in stainless steel alloys. Alloys containing niobium are used in rockets and jet engines and oil and gas pipelines.
- It is also used in making jewellery.
