Tantalum (Ta; atomic weight 180.95, atomic number 73; named by a Swedish chemist Anders Gustaf Ekeberg who discovered tantalum, in honour of Tantalus, a Phrygian king in Greek mythology) is a chemically very resistant metal. At low temperatures (< 150 °C) tantalum is almost completely immune to chemical attack.

Tantalum capacitor is very thin and has a relatively high permittivity dielectric layer. We can distinguish it from other types of conventional and electrolytic capacitors since capacitance per volume is very high, and the weight is lower.

Tantalum (atomic number 73, symbol Ta) is a hard, heavy metal that is grayish silver in color.The element was discovered by the Swedish chemist Anders Ekeberg in 1802 while Christian Blomstrand proved that niobium and tantalum are different elements in 1864.

Tantalum is completely immune to body liquids and is a nonirritating material. It has, therefore, found wide use in making surgical appliances. Tantalum oxide is used to make special glass with high index of refraction for camera lenses. The metal has many other uses. Costs The price of (99.9%) tantalum in Dec. 1988 was about $50/oz.

The world's largest tantalum deposits can be found in Australia, Brazil, and a number of African countries. The ore is refined using a variety of methods to obtain concentrates of approximately 70% (Ta, Nb) 2 O 5 .

It has 2 natural isotopes - Ta-181 and Ta-180m. Ta-181 is a stable isotope, and Ta-180m is a stable isomer and it is the only naturally occurring one. Tantalum is used in surgery as it is unreactive. This element forms a protective oxide layer in air. Tantalum was identified by Ekeberg in 1802 and was isolated by Jons J. Berzelius in 1820.

Tantalum is a chemical element represented by the symbol Ta and the atomic number is 73. Formerly known as tantalum, it is named after Tantalus, a Greek mythological villain. Tantalum is a highly corrosion-resistant, rare, strong, blue-grey, lustrous transition metal.

History. Named after Tantalos, a Greek a mythological character, father of Niobe.Discovered in 1802 by Ekeberg, but many chemists thought niobium and tantalum were identical elements until Rowe in 1844, and Marignac, in 1866, showed that niobic and tantalic acids were two different acids. The early investigators only isolated the impure metal. The first relatively pure ductile …

Chemical element, Tantalum, information from authoritative sources. Look up properties, history, uses, and more.

It has an atomic number of 73, and an atomic weight of just under 181. It always takes a valence of 5, so, for example, its oxide contains two atoms of tantalum and five of oxygen. In its pure state, tantalum is a grey-blue metal, which can be polished to a silvery sheen.

Tantalum can also be used for making thin lines of sewing tissue medically. Tantalum oxide (tantalum pentoxide, Ta2O5) can't react with any acid, so it's a good coating material.

Tantalum atomic number is seventy-three. This blue-grey metal is very hard and also has a super high melting point. Uranium. 9 – Uranium (Density Per Cubic cm: 19.05g) Discovered in 1789 by German chemist Martin H. Klaprot, poor uranium was not fully isolated until almost a hundred years later in 1841!

The first data column contains the total number of minerals listed with Tantalum and the element listed for that row. The second data column lists this number as a percentage of all minerals listed with Tantalum. The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row.

The electronegativity of Tantalum is: χ = 1.5. In general, an atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.

Tantalum is a blue-gray transition metal with element symbol Ta and atomic number 73. Because of its hardness and corrosion resistance, it is an important refractory metal and is widely used in alloys.
