2025年3月3日 · zirconium (Zr), chemical element, metal of Group 4 (IVb) of the periodic table, used as a structural material for nuclear reactors. zirconium Zirconium rod. Zirconium, obscure before the late 1940s, became a significant engineering material for nuclear energy applications because it is highly transparent to neutrons.

Zirconium is the 40th element in the periodic table and the symbol is ‘Zr’. Zirconium has an atomic number of 40, which means that its atom has 40 electrons around its nucleus. The electron configuration of zirconium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 2 which means that the first two electrons enter the 1s orbital.

Zirconium is a chemical element of the periodic table with chemical symbol Zr and atomic number 40 with an atomic weight of 91.2242 u and is classed as transition metal and is part of group 4 (titanium group). Zirconium is solid at room temperature.
