A Group 5 element is a chemical element in the fifth group in the periodic table. In the modern IUPAC nomenclature, Group 5 of the periodic table contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.
The lighter three Group 5 elements occur naturally and do share similar properties; all three are hard refractory metals under standard conditions. The fourth element, dubnium, has been synthesized in the laboratory, but it has not been found occurring in nature, with half-life of the most stable isotope, dubnium-268, being only 28 hours, and other isotopes even more radioactive. To date, no experiments in a supercollider have been conducted to synthesize the next member of the group, either unpentpentium (Upp) or unpentseptium (Ups). As unpentpentium and unpentseptium are both late period 8 elements it is unlikely that these elements will be synthesized in the near future.

Famous quotes containing the words group and/or element:
“If the Russians have gone too far in subjecting the child and his peer group to conformity to a single set of values imposed by the adult society, perhaps we have reached the point of diminishing returns in allowing excessive autonomy and in failing to utilize the constructive potential of the peer group in developing social responsibility and consideration for others.”
—Urie Bronfenbrenner (b. 1917)
“Luckily for us, now that steam has narrowed the Atlantic to a strait, the nervous, rocky West is intruding a new and continental element into the national mind, as we shall yet have an American genius.”
—Ralph Waldo Emerson (1803–1882)
