Dubnium: description Your user agent does not support the HTML5 Audio element. It is a radioactive element, and not found in any naturally occurring states. Since Dubnium is not produced in high amounts and it … Dubnium does not occur naturally on … Dubnium is a synthetic element that was discovered in 1970. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. Dubnium is an artificial element and was first created and thus found in a laboratory in the city of Dubna. The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. History and Discovery. Dubnium is a member of the d-block series and is a transactinide element. It is a radioactive synthetic metal and has only been produced in tiny amounts. Its chemistry and appearance are not known with any certainty, although the chemistry is believed to be similar to tantalum. Dubnium is harmful due to its radioactivity. Periodic Table of Elements Element Dubnium - Db. Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. It has never been found naturally and only a small number of atoms have been produced in laboratories. Abundance and Isotopes. Abundance earth’s crust: nil Dubnium is too rare to have any commercial or industrial application. This greatly limits the extent of research on dubnium. This greatly limits the extent of research on dubnium. Characteristics: Dubnium is a transactinide or super-heavy element. They bombarded atoms of americium-243 with ions of neon-22, forming atoms of dubnium-260 and five free neutrons and atoms of dubnium-261 and four free neutrons. Contents.
