Electron Affinity. Related Questions. Dubnium should share most properties, such as its valence electron configuration and having a dominant +5 oxidation state, with the other group 5 elements, with a few anomalies due to relativistic effects. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. ... we know a bit about the chemistry of dubnium.

Electron Configuration: Value is a guess based on periodic table trend. Its longest-lived known isotope has an atomic number of 262 with a half life of 34 seconds. Researchers there bombarded an americium-243 target with neon-22 ions. It wasn't until 1997 it was decided the element should be named Dubnium (Db) for the Dubna research facility -- the location where the element was initially synthesized. Electron Configuration. At present, little is known about its properties and it has no practical uses. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. The predicted electron configuration of dubnium is [Db]5f14.6d3.7s2. It does not have any isotopes considered to be natural. It has a Body centered cubic crystalline structure. Dubnium's most stable isotope, dubnium-268, has a half-life of about 32 hours and decays through spontaneous fission.
This limits the extent of research on dubnium Up to date, curated data provided by Mathematica's ElementData function from Wolfram Research, Inc. Electronegativity of Dubnium is —. Due to the small amounts produced and its short half-life, there are currently no uses for dubnium outside of basic scientific research. The other isotopes are synthetic in nature and have their mass numbers ranging from 256 to 270. Electron Affinity of Dubnium is — kJ/mol. Credit for the discovery of dubnium is still under debate.Dubnium's most stable isotope, dubnium-268, has a half-life of about 32 hours and decays through spontaneous fission. The first isotope to be synthesized was 261 Db in 1968.
The metal is produced in small amounts artificially.
