It Is Tantalum(Ta).
Zirconium (Zr)
That element would be carbon.
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 phosphorous (P) is located in group 15, period 2.
The atomic number of the element with the symbol Li, located in period 3 on the periodic table, is 3.
Ta -- tantalum. The element formerly called columbium is now Nb -- niobium,
niobium period
Zirconium (Zr)
That element would be carbon.
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.
they are Yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium palladium, silver and cadmium.

Chromium
Iodine, element number 53 is the halogen (Group 17) element in period 5.
In, Sn, Sb, Te, I or Xe are all representative (main group) elements in the 5th period which is numbered on the left (1-7) and a "period" is the horizontal rows.
The atomic number of the element with the symbol Li, located in period 3 on the periodic table, is 3.
