Ununquadium ( IPA: /ˌjuːˌnʌnˈkwɒdiəm/), or eka- lead, is the temporary proper noun of a radioactive element in the periodic table that has the temporary symbol Uuq and has the atomic number 114.

History

The discovery of ununquadium in December 1998 was reported in Jan 1999 by scientists at Dubna ( Articulation Institute for Nuclear Research) in Russian federation. The same team produced another isotope of Uuq iii months later and confirmed the synthesis in 2004 and 2006.

In 2004 in the Joint Institute for Nuclear Research the synthesis of this element was confirmed by some other method (the chemic identifying on concluding products of decay of element).

Ununquadium is a temporary IUPAC systematic chemical element name. Some have termed it eka-lead, every bit its backdrop are conjectured to be similar to those of lead. It is expected to be a soft, dense metal that tarnishes in air, with a melting signal around 200 degrees Celsius.

Synthesis

Ununquadium tin can be synthesized by bombarding plutonium 244 targets with calcium 48 heavy ion beams.

Synthesis of isotope 298

Manufacturing Ununquadium-298 would be very difficult, because nuclei summing to 114 protons and 184 neutrons are non available in weighable quantities.

Even so it may be possible to generate the isotope 298 of Element 114, if nuclear transfer reactions tin can be achieved. One of these reactions may be: ²⁰⁴Hg + ¹³⁶Xe → ²⁹⁸Unq + ⁴⁰Ca + 2n

Stable ununquadium

Ununquadium does not occur naturally on the earth—it is entirely synthesized in laboratories. All isotopes of ununquadium synthesized so far are neutron-poor. This ways that they contain significantly-fewer neutrons than 184, which is a hypothetical "magic number" of neutrons for greater stability (isotope Uuq-298). Neutron-poor also indicates that the isotopes disuse either past spontaneous fission, or by 1 of the ii processes that convert a proton into a neutron, yielding element 113.
