What is tantalum chemical formula?
Ta
Tantalum is a chemical element with symbol Ta and atomic number 73. Classified as a transition metal, Tantalum is a solid at room temperature.
Is tantalum a chemical element?
tantalum (Ta), chemical element, bright, very hard, silver-gray metal of Group 5 (Vb) of the periodic table, characterized by its high density, extremely high melting point, and excellent resistance to all acids except hydrofluoric at ordinary temperatures.
What is tantalum used for?
Tantalum is used in a variety of alloys to add high strength, ductility and a high melting point. When drawn into a fine wire, it’s used as a filament for evaporating metals such as aluminum. More than half of tantalum’s use is for electrolytic capacitors and vacuum furnace parts.
What is NB in chemistry?
niobium (Nb), chemical element, refractory metal of Group 5 (Vb) of the periodic table, used in alloys, tools and dies, and superconductive magnets. Niobium is closely associated with tantalum in ores and in properties.
How do you identify a tantalum capacitor?
Tantalum capacitors are innately polarized capacitors with positive and negative lead and are appropriate with DC supplies. The polarity and markings on the capacitors make it easy to identify the anode and cathode. Two bands and a positive sign helps in identifying the value of capacitance and maximum working voltage.
What is tantalum ring?
Tantalum is a very dense, malleable metal making it easy to work with similar to gold. It has a rich slate bluish-gray color. Tantalum rings are manufactured with the metal in its purest form, making them completely hypo-allergenic, resistant to breakage and ultimately the most precious of all contemporary metals.
Is tantalum a metal?
Tantalum belongs to a class of metals known as refractory metals, which are defined by their strong resistance to heat and wear. It has a melting point of 5,463 °F (2,996 °C), the fourth highest of all metals.
What color is tantalum?
Once extracted, pure tantalum is a hard blue-gray lustrous metal.

What element family is tantalum?
Tantalum is a transition metal in Group 5 (VB) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Tantalum is one of the most inert metals known.
How is tantalum used in the chemical industry?
The Uses of Tantalum in the Chemical Industry In the chemical industry, tantalum can be used to replace stainless steel in the equipment for making various inorganic acids, and the life of the equipment can be increased by dozens of times compared with the use of stainless steel.
Is tantalum a non metal?
Tantalum is a metal. no, Tantalum is a metal…. a gray, hard, rare, metallic element occurring in columbite and tantalite and usually associated with niobium: used, because of its resistance to corrosion by most acids, for chemical, dental, and surgical instruments and apparatus.
What is the common oxidation number for tantalum?
Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. In compounds of tantalum (where known), the most common oxidation numbers of tantalum are: 5.
What is tantalum metal?
Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum.
