What is Zirconium atom?

     

Zirconium is a chemical element with the symbol Zr and atomic number 40.  The name Zirconium is taken from the name of the mineral zircon the most important source of zirconium.  It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and to a lesser extent, titanium.  Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion.  

     Zirconium forms a variety of inorganic and organometallic compounds such as zirconium dioxide and zirconocene dichloride, respectively.  Five isotopes occur naturally, three of which are stable.  Zirconium compounds have no known biological role.
