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:
“Once it was a boat, quite wooden
and with no business, no salt water under it
and in need of some paint. It was no more
than a group of boards. But you hoisted her, rigged her.
She’s been elected.”
—Anne Sexton (1928–1974)
“We have a great deal more kindness than is ever spoken. Maugre all the selfishness that chills like east winds the world, the whole human family is bathed with an element of love like a fine ether.”
—Ralph Waldo Emerson (1803–1882)
