Niobium was found in 1801

supplement. Niobium and Tantalum are often found together. Niobe was the daughter of Tantalus, who had some bad luck.

In Greek mythology, he was under a grape vine, but when he reached for fruit, it retreated. Nearby was a jug of water, but when reached for, it also retreated. [Very ROUGH interpretation of fable!]

Anyway, when this metal (Ta) was found, no real use could be found for it hence the name (from tantalize). It is also biologically inert, and in this role was used for metal plates covering trephining etc holes in the head.

Nowadays, its fine oxide coating makes it valuable for tantalum capacitors in electronics.

How many moles are in 237g of niobium?

To determine the number of moles in 237g of niobium, we need to use the molar mass of niobium, which is approximately 92.91 g/mol. By dividing 237g by the molar mass of niobium, we find that there are approximately 2.55 moles of niobium in 237g.


How niobium separated from other materials found with it?

Niobium is typically separated from other materials through a process called fractional crystallization using solvents. This process involves dissolving the compound mixture in a solvent and then gradually cooling the solution to separate out the niobium compounds based on their differing solubilities. This allows for the isolation and purification of niobium from other materials.
