 Tantalum - Wikipedia
A chemical element, in the periodic table tantalum has the symbol Ta and atom number 73.
It was discovered in 1802 by Anders Ekeberg, in Sweden.
Its name is derived from the Greek word "Tantalos" meaning "father of Niobe," a reference to tantalum's close relationship to niobium on the periodic table.

 Tantalum corrosion
marked the 200th anniversary of the discovery of tantalum by Anders Gustav Ekeberg of Sweden using an ore sample from Kimito, Finland.
He named it after King Tantalus of Phrygia, from Greek mythology, who was condemned to eternal frustration by standing up to his neck in water, which receded when he tried to drink it.
Ekeberg thought this name was fitting because of the difficulty he had in isolating it.

 Tantalum - Wikipedia, the free encyclopedia
The metal is also used to make vacuum furnace parts.
Tantalum (Greek Tantalus, mythological character) was discovered in Sweden in 1802 by Anders Ekeberg and isolated in 1820 by Jöns Berzelius.
Many contemporary chemists believed niobium and tantalum were the same elements until 1844 and later 1866 when researchers showed that niobic and tantalic acids were different compounds.

He concluded his analysis in 1794 and named this new earth ytterbia Kongl.
His analysis was confirmed three years (1797) later when Anders Gustaf Ekeberg (1767-1813) analysed a larger sample.
In the decades after Antoine Lavoisier developed the new chemistry built on the concept that earths could be reduced to their elements, the discovery of a new earth (with name ending in "a") was regarded as equivalent to discovering the element within.

In 1809 William Hyde Wollaston claimed to have shown Columbium and Tantalum were identical.
