Also known as Db, element 105, hahnium, unnilpentium, Unp

Dubnium is a synthetic chemical element; it has symbol Db and atomic number 105. It is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 16 hours. This greatly limits extended research on the element.

AI overview

Dubnium is a human-made chemical element (symbol Db, atomic number 105) that is extremely radioactive and decays very quickly, with its most stable form lasting only about 16 hours. Because it breaks down so rapidly, scientists have difficulty studying it in detail, which limits what we can learn about this element's properties and potential uses.
