niobium period
Zirconium (Zr)
Ruthenium is located in period 6 beneath niobium on the periodic table. It has the atomic number 44.
One example of an element that belongs to both group 5B (Group 15) and period 5 of the periodic table is antimony (Sb). Antimony has 5 valence electrons, placing it in group 5B, and it is in period 5, indicating the energy level of its electron shells.
The element Niobium is in Group 5 along with Vanadium, Tantalum, and Dubnium. It is actually very difficult to distinguish from Tantalum.
Promethium is placed in the period 6 of the periodic table, lanthanoids family.
Vanadium, niobium , tantalum
sex on the beach lol jk its 6
Niobium (Nb), or columbium, is a shiny gray metal, but it becomes bluish when exposed to air at room temperature for a period of time. A link to the Wikipedia article on niobium is provided.
Tin belongs to group 14, carbon family, period 5. Neon belongs to group 18, noble gases, period 2.
Seaborgium: group 6, period 7 - in the periodic table of Mendeleev.
The three main isotopes of niobium are niobium-93, niobium-95, and niobium-96. These isotopes are stable and occur naturally in different abundances. Niobium-93 is the most abundant isotope, followed by niobium-95 and niobium-96.
They are niobium-titanium or niobium-tin intermetallic compounds.
