The element Tantalum, symbol and period table values and description including atomic weight, Fluorescence yield,edge jumps, and Edge Energies (keV).

Tantalum is a chemical element that is classified as a transition metal in the periodic table of elements. It is a heavy bluegrey metallic appearance known by the chemical symbol Ta . It was first discovered in 1802 by Anders G. Ekeberg and arranged by Jöns Berzelius in 1820.

Aug 07, 2013· Introduction. Tantalum is a chemical element with Ta as its symbol. It belongs to group 5, periodic number 6 of the periodic table. Its atomic number is 73. Tantalum is a silvery metal that is soft in its pure form. It is a strong and ductile metal and at temperatures below 150°C (302°F), this metal is quite immune to chemical attack.

the general term for shiny, durable, malleable, ductile elements found to the left of the stair steps on the periodic table. nonmetals the general term for dull, brittle (if solid), probably gaseous or liquid substances found to the right of the stair steps on the periodic table.

Tantalum is mined from various regions around the world, with most tantalum coming from either South America or Australia. It is often found together with nobium as well as the radioactive elements thorium and uranium, and has to be extracted from these other elements. Tantalum is naturally grayish in color with a hint of blue.

Niobium, formerly known as columbium, is a chemical element with symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, crystalline, ductile transition metal, often found in the minerals pyrochlore and columbite, hence the former name "columbium".

However, in thermodynamic terms, tantalum is a base metal which can nevertheless form stable compounds with a wide variety of elements. When exposed to air, tantalum forms a very dense oxide layer (Ta 2 O 5 ) which protects the base material from aggression.

Atomic Number of Tantalum. Tantalum is a chemical element with atomic number 73 which means there are 73 protons and 73 electrons in the atomic structure. The chemical symbol for Tantalum is Ta. Atomic Mass of Tantalum. Atomic mass of Tantalum is u.

Isotope: Atoms of the same element with the same atomic number, but different number of neutrons. Isotope of an element is defined by the sum of the number of protons and neutrons in its nucleus. Elements have more than one isotope with varying numbers of neutrons.

Element 35: Bromine. Bromine is a chemical element which is of deep red, noxious liquid and one of the members of the halogen elements of the periodic table. This element is reddish brown liquid added with an appreciable vapor pressure at room temperature. Bromine vapors show amber color similar to .

Tantalum: Tantalum. A rare metallic element, atomic number 73, atomic weight, symbol Ta. A rare metallic element, atomic number 73, atomic weight, symbol Ta. It is a noncorrosive and malleable metal that has been used for plates or disks to replace cranial defects, for wire sutures, and for making prosthetic devices.

Chemistry. a chemical element that is a rare metal of the vanadium family, having the symbol Ta, the atomic number 73, an atomic weight of, a melting point of 299°C, and a boiling point of 5560°C; a malleable gray solid that is resistant to corrosion, used for electric light filaments and as a catalyst.

Sep 03, 2014· The highlighted elements are considered the metal elements. Most elements can be considered metals. They are grouped together in the middle to the lefthand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides. Properties of Metals.

Tantalum is used to make a variety of alloys with desirable properties such as high melTantalumg point, high strength, good ductility, etc. Tantalum has a good "gettering" ability at high temperatures, and tantalum oxide films are stable and have good rectifying and dielectric properties.

Tantalum is obtained chiefly from the mineral tantalite, although it also occurs in euxenite, samarskite, and some other rare minerals. The major sources of tantalum ore are Australia, Brazil, and Canada. Tantalum is almost always found in association with niobium; separation of the two metals is difficult.

Tantalum (atomic symbol: Ta, atomic number: 73) is a Block D, Group 5, Period 6 element with an atomic weight of The number of electrons in each of tantalum's shells is [2, 8, 18, 32, 11, 2] and its electron configuration is [Xe] 4f 14 5d 3 6s 2 .

Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, an antihero from Greek mythology. Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant.

Tantalum is the 73rd element on the periodic table found in group 5 and period 6. It is a transition metal with 73 protons in its nucleus. The chemical symbol for tantalum is Ta .

Description Rare, gray, heavy, hard but ductile, metal with a high melting point. Uses Often used as an economical substitute for platinum. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power.
