  • Tantalum Ta (Element) - PubChem

    Tantalum pentoxide (Ta 2 O 5 ), one of tantalum's compounds, is a dielectric material and is used to make capacitors. It is also used to make a glass with a high index of refraction that is used in camera lenses. A composite consisting of tantalum carbide (TaC) and graphite is one of the hardest materials known and is used on the cutting edges

  • Periodic Table of Elements - Atomic Number, Atomic Mass

    The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.

  • Element List - Atomic Number, Element Name and Symbol

    May 02, 2020· Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix. For example, element 120 has the temporary name unbinilium.

  • Tantalum (Ta) - Atomic Number 73

    Tantalum (Ta) is a gray coloured metal that has the atomic number 73 in the periodic table. It is a Transition metal in Group 5. It has the symbol Ta. Tantalum is a blue gray very hard metal that has the fourth highest melting point of metallic elements. It was discovered in

  • Atomic Number of Elements in Periodic Table

    Atomic Number of Elements in Periodic Table. We remember from our school chemistry course that every element has its own specific atomic number.It is the same as the number of protons that the atom of each element has, so sometimes atomic number is called proton number.It is always the whole number and it ranges from 1 to 118, according to the number of the element in the Periodic Table.

  • Tantalum - Element information, properties and uses
