Niobium

= ​Niobium = By: ​ David


 * Atomic Number: ** 41


 * Protons: ** ​ 41


 * Electrons: ** 41


 * Neutrons: ** 52


 * Average Atomic Mass: ** 92.906


 * Isotopes: ** ​ There is only one stable isotope of niobium: Nb-93.


 * Discovery: ** ​ It was discovered by Charles Hatchett in 1801. He found it in a mineral sample that came from Massachusetts, United States.


 * Name: ** ​ Niobium was originally named "columbium," but the IUPAC wanted it to be niobium, a name used by Heinrich Rose in 1846. The name also originated from Niobe, daughter of the Greek god Tantalus.


 * Uses: ​** Niobium is found in nuclear reactors, because it doesn't react with uranium and is extremely non-corrosive. Big amounts of niobium are used in advanced air frame systems. With other elements, it can form superconductors.


 * Interesting Facts ** : ​ Although niobium is the official name for the element, some people refer to it as columbium (Cb). It's very hard to distinguish it from tantalum (notice the relationship between tantalum and niobium, the Greek god Tantalus and his daughter Niobe). When exposed to air at room temperature, it develops a bluish cast.
