systematic element name

Eka is a prefix for a chemical element which is listed in the periodic table under another element. The prefix eka- was used especially to name as yet undiscovered elements. For example germanium was called ekasilicon until its discovery. The prefix originates from the Sanskrit word "eka" meaning "one" and was coined by Dmitri Mendeleev. The prefixes dvi- and tri- from the Sanskrit prefixes meaning "two" and "three" respectively, have been used for undiscovered elements two or three places in the periodic t ...

Ununquadium (eka-lead) is the temporary name of a radioactive chemical element in the periodic table that has the temporary symbol Uuq and has the atomic number 114. Ununquadium - History. In January 1999, ununquadium was reported informally by scientists at Dubna (Joint Institute for Nuclear Research) in Russia. The same team produced another isotope of Uuq three months later. Since then, no one has seriously challenged the finding. Ununquadium is a temporary IUPAC systematic element name. Some have ...

Dubnium (formerly also called Eka-Tantalum, Hahnium and Unnilpentium) is a chemical element in the periodic table that has the symbol Db and atomic number 105. This is a highly radioactive synthetic element whose most stable isotope has a half life of 16 hours (dubnium-268). This relatively high stability compared to the surrounding elements on the periodic table gives evidence that by manipulating the number of neutrons in a nucleus, ...

On February 1, 2004, ununtrium and ununpentium were reported by a team composed of Russian scientists at Dubna (Joint Institute for Nuclear Research), and American scientists at the Lawrence Livermore National Laboratory. Their discovery of the element still awaits confirmation. [1] On September 28, 2004, a team of Japanese scientists declared that they succeeded in synthesizing the element. [2] (Morita et al, Experiment on the Synthesis of Element 113 in the Reaction 209Bi(70Zn, n)278113, J. Phys. Soc. Jpn., Vol. 73, N ...

On February 1, 2004, the synthesis of ununpentium and ununtrium were reported in Physical Review C by a team composed of Russian scientists at Dubna University's [1] Joint Institute for Nuclear Research [2], and American scientists at the Lawrence Livermore National Laboratory. Their discovery of the element still awaits confirmation. [3] The team reported that they bombarded americium (element 95) with calcium (element 20) to produce four atoms of ununpentium (element 115). These atoms, they report, decayed to ununtrium (element 113) in a fraction of a second. The ununtrium produced then existed for 1.2 seconds ...

Element 106 was discovered almost simultaneously by two different laboratories. In June 1974, a Soviet team led by G. N. Flerov at the Joint Institute for Nuclear Research at Dubna reported producing an isotope with mass number 259 and a half-life of 0.48 s, and in September 1974, an American research team led by Albert Ghiorso at the Lawrence Radiation Laboratory at the University of California, Berkeley reported creating an isotope with mas ...

Since then, no one has seriously challenged the finding. Ununquadium is a temporary IUPAC systematic element name. Some have termed it 'eka-lead', as its properties are conjectured to be similar to those of lead. ...

The name unbinilium is used as a placeholder, such as in scientific articles about the search for element 120. Transuranic elements beyond plutonium are always artificially produced, and usually end up being named for a scientist or the location of a laboratory that does work in atomic physics. See systematic element name. ...

Meitnerium was first synthesized on August 29, 1982 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research at Darmstadt. The team did this by bombarding a target of bismuth-209 with accelerated nuclei of iron-58. The creation of this element demonstrated that nuclear fusion techniques could be used to make new, heavy nuclei. The name meitnerium was suggested in honor of the Austrian-Swedish physicist and mathematician Lise Meitner, but there was an element naming contr ...

The appearance of this element is unknown, however it is most likely silvery-white or gray and metallic. If sufficient amounts of lawrencium were produced, it would pose a radiation hazard. Very little is known about the chemical properties of this element but some preliminary work on a few atoms has indicated that it behaves similarly to the actinides. Element 103 is a d-block element analogous to lutetium and therefore is increasingly being placed with the other d-block elements in the transition metal chemical series, but it is still most o ...

It was first created at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany on December 8, 1994. Only three atoms of it were observed (all 272Rg), by the fusion of bismuth-209 and nickel-64 in a linear accelerator. (Nickel was bombarded onto the bismuth target.) The name roentgenium was accepted as a permanent name on November 1, 2004 in honour of Wilhelm Roentgen; before this date, the element was known under the temporary IUPAC systematic element name unununium. Some res ...
