Its symbol is Db and it belongs to the group of transition metals and its usual state in nature is unknown. The Russian discovery team (1969) proposed the name... Dubnium is a super-heavy … They can also be used for Dubnium advertisement and marketing. The chemical symbol for Dubnium is Db . Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. Electronegativity according to Pauling If a sufficient amount were ever produced, its chemical properties are expected to be similar to that of the transition metals. This article will focus on things Wikipedia does not stress: heavy isotopes and formation. Dubnium is a super-heavy or transactinide element. The 13 known radioisotopes are from 255 Db to 270 Db, and 1–3 isomers. In the 1960s, microscopic amounts of dubnium were produced in laboratories in the former Soviet Union and in California. Dubnium (named after Dubna, Russia) was reportedly first synthesized in 1967 at the Joint Institute for Nuclear Research in Dubna, Russia (reportedly producing nuclide 260 105 and nuclide 261 105 by bombarding 243 Am with 22 Ne).In late April 1970 researchers led by Albert Ghiorso working at the University of California, Berkeley had positively identified element 105. History . Dubnium is located at position 105 on the periodic table. It occurs as a synthetic element in nature, … Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. It occurs as a synthetic element in nature, and it is artificially produced by the bombardment of the californium-249 with the nuclei nitrogen-1. So, because of that, both groups gave Dubnium different names. Dubnium does not have any application and little is known about it. However, before the name of Dubnium was approved, both research teams argued the who should receive the discovery credit of Dubnium. Dubnium is a highly radioactive element with only one single stable isotope dubnium-268 which has a half-life measuring about only 32 hours and gets decayed through the process of spontaneous fission. The metal behaves as a solid at temperatures of 20o °C. The bombardment of it can make many isotopes of it with the Heavy Ion Linear Accelerator.
