October 20, 2018 Leave a Comment

Electron Configuration For Tantalum: Tantalum is a chemical element which has a chemical symbol, Ta. Atomic number 73. Prior to this, it was known as tantalum. Its name has come from Tantalus, who was a villain from Greek mythology. It is a blue-grey, hard, lustrous transition metal and rare metal which is highly corrosion-resistant.

Electron Configuration For Tantalum

Tantalum is a part of the refractory group metal, that is majorly used as minor components of alloys. The chemical inertness of tantalum makes it a very valuable material for lab equipment and also a substitute for platinum. Today its main use is in tantalum capacitors in electronic equipment for example DVD players, mobile phones, computers and video game systems.

It always together with the chemically similar niobium, occurs in the mineral groups columbite, tantalite and coltan. Today we will tell you about the electron configuration of the Ta.

Electron Configuration For Hafnium: Hafnium is a chemical element that has a chemical symbol Hf. The atomic number of Hafnium is 72. A silvery grey, lustrous, tetravalent transition metal. It chemically resembles zirconium and it is found in many zirconium minerals.

The existence of Hafnium was predicted by in 1869 by Dmitri Mendeleev. Although until 1923, it was not identified by Hevesy and Coster, making it the last stable element to be discovered. It is named after Hafnia, that is the Latin name for Copenhagen, where it was discovered.

It is used in electrodes and filaments. Some semiconductors of Hafnium fabrication processes use its oxide for integrated circuits at 45 nm. Some superalloys used for special applications contain hafnium in combination with titanium, niobium, or tungsten. Today we will tell you the electron configuration of the Hafnium.

Electron Configuration For Lutetium: Lutetium is a chemical element that has chemical symbol Lu. The atomic number of Lutetium 71. It is a white silvery metal, that resists corrosion in dry air and not in the moist air. It is the last element of the lanthanide series. Traditionally, it is counted among the rare earth elements.

Sometimes It is considered as the first element of the 6th-period transition metals, however, lanthanum is more often considered as such. It was independently discovered by French scientist Georges Urbain, Austrian mineralogist Baron Carl Auer von Welsbach, and American chemist Charles James in 1907.

These researchers found that lutetium as an impurity in the mineral called ytterbia, that was previously thought to consist entirely of ytterbium. There was a dispute on the priority of the discovery which occurred shortly after, with Welsbach and Urbain accusing each other of publishing results that are influenced by the published research of the other; then naming honour went to Urbain because he had published his results earlier. Today we are going to tell you about the electron configuration of Lutetium.

Electron Configuration For Seaborgium: Seaborgium is a synthetic chemical element which has a chemical symbol Sg. The atomic number of Seaborgium is 106. It got its name after the American nuclear chemist Glenn T. Seaborg. Since it is a synthetic element, it Is only created in a laboratory but is not found in nature. It is also radioactive and the most stable known isotope, ²⁶⁹Sg.

It has a half-life of approx 3.1 minutes. It is an ad-block transactinide element, in the periodic table of the elements. It is the member of the 7th period which belongs to the group 6 elements as it is the fourth member of the 6d series of transition metals. Chemical experiments have confirmed that it behaves as the heavier homologue than tungsten in group 6.

The chemical characteristics of seaborgium are shown only partly, but they are compared well with the chemistry of the other elements of group 6. A few atoms of seaborgium were produced in laboratories in the Soviet Union and in the United States in 1974.

The priority of its discovery and after that the naming of the element was disputed between American scientists and Soviet, and it was not until 1997 that IUPAC (International Union of Pure and Applied Chemistry) confirmed seaborgium as the official name for the element. It is one of only two elements that are named after a living person at the time of naming, the other on is oganesson, element 118.
