On This Day In Chemistry

November 26th

English chemist Charles Hatchett announced the discovery of columbium (Cb) to the Royal Society on this day in 1801

Now known as niobium (Nb), this metal element is very similar to tantalum (Ta), and was in fact confused with it during parts of the 19th century. This lead to it being renamed niobium after the daughter of Tantalus in Greek mythology.
