Zirconium is used as a getter in vacuum tubes, as an alloying agent in steel, in surgical appliances, photoflash bulbs, explosive primers, rayon spinnerets, lamp filaments, etc. It is used in poison ivy lotions in the form of the carbonate as it combines with urushiol.
The process used for the purification of zirconium is called the Kroll process. This process involves converting zirconium tetrachloride into metallic zirconium through a reduction process using magnesium.
It is possible as zirconium alloys (zirconium metallic glasses) or zirconium dioxide ceramics.
The alloy zirconium-aluminium is used for some components for planes.
Zirconium does have radioactive isotopes, but the main ones used in industry are not radioactive.
Zirconium is No. 40 in the Periodic Table. The '40' tells us the position of zirconium in the table, the number of protons in an atom , and the number of electrons in a neutrally charged atom. So the answer to you question is '40'.
Zirconium is used as a white pigment in photographic paper to improve its reflective properties and enhance image quality. It is also used in the manufacture of certain chemicals used in the development process of photographs. Additionally, zirconium compounds are used in the production of light-sensitive emulsions in photography.
Zirconium is found in a wide range of compounds, with estimates placing the number of known zirconium compounds in the thousands. These compounds can include zirconium dioxide, zirconium carbonate, zirconium nitrate, and many others used in various industries such as ceramics, electronics, and nuclear reactors.

When zirconium and nitrogen react, they can form compounds such as zirconium nitride (ZrN). Zirconium nitride is a hard, ceramic material often used as a coating to improve the wear and corrosion resistance of various surfaces.
The toxicity of zirconium is not very important; only the inhalation of zirconium and zirconium compounds powders is dangerous (as for many other materials) - leading to pneumoconioses. Also zirconium can be pyrophoric at high temperatures, in powdr form. Zirconium is used for surgical implants, stomatology - as zirconium dioxide, im some cosmetics. No nutitional use.
Zirconium is commonly used in nuclear reactors for its resistance to corrosion. It is also used in ceramics, refractory materials, and as an opacifier in glazes and enamels. In addition, zirconium compounds are used in catalysts, propellants, and in the production of high-performance alloys.
Zirconium sponge is a highly pure form of zirconium metal produced through a chemical reduction process. It has a high surface area and is commonly used as a raw material for manufacturing zirconium products such as alloys, ceramics, and chemicals.
