Tantalum

Tantalum (Ta)

Tantalum is the 73rd element in the periodic table and has a symbol of Ta and atomic number of 73. It has an atomic weight of 180.94788 and a mass number of 181. Tantalum has seventy-three protons and one hundred eight neutrons in its nucleus, and seventy-three electrons in six shells. It is located in group five, period six and block d of the periodic table. Heavy blue-grey metallic transition element. Ta-181 is a stable isotope, and Ta-180 is a radioactive isotope, with a half-life in excess of 10^7 years. Used in surgery as it is unreactive. Forms a passive oxide layer in air. Identified in 1802 by Ekeberg and isolated in 1820 by Jons J. Berzelius.

Tantalum single crystal and 1cm3 cube

History

Tantalum was discovered in Sweden in 1802 by Anders Ekeberg in the minerals tantalite from Finland and yttrotantalite from Sweden. Unfortunately, William Hyde Wollaston claimed Ekeberg's new element was actually niobium, which had also been discovered in 1802. In 1846, German chemist Heinrich Rose finally proved beyond doubt that tantalum and niobium were different elements. Named after Tantalos, a Greek mythological character, father of Niobe

DiscoverersAnders Ekeberg
Discovery LocationSweden
Discovery Year1802
Etymology (Name Origin)From king Tantalus of Greek mythology, father of Niobe.
PronunciationTAN-te-lem (English)
Tantalum is considered to be non-toxic
Tantalum occurs principally in the mineral columbite-tantalite

Uses

Tantalum is used in the electronics industry for capacitors and high power resistors. The high melting point and oxidation resistance lead to the use of the metal in the production of vacuum furnace parts. Tantalum oxide is used to make special glass with high index of refraction for camera lenses. Often used as an economical substitute for platinum. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power. It and its alloys are corrosion and wear resistant so it is used to make surgical and dental tools.

Sources

Chiefly occurs in the mineral tantalite. Always found with niobium.
