Zirconium is a chemical element; it has symbol Zr and atomic number 40. First identified in 1789, isolated in impure form in 1824, and manufactured at scale by 1925, pure zirconium is a lustrous transition metal with a greyish-white color that closely resembles hafnium and, to a lesser extent, titanium .
This infobox must distinguish between three typical (exemplary) elements: E118 (regular element), E119 and E121. Handling of these element infoboxes is hardcoded in the meta-infobox, set by |number= (Z). Theoretical element: above-header shows; Theoretical element Applied: when element is theoretical (E119 and higher).
Group 4 is the second group of transition metals in the periodic table. It contains only the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). ). The group is also called the titanium group or titanium family after its lightest me
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Zirconium is a chemical element with the symbol Zr and atomic number 40. The name of zirconium is taken from the mineral zircon. Its atomic mass is 91.224. It is a lustrous, gray-white, strong transition metal that resembles titanium.
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.

Naturally occurring zirconium (40 Zr) is composed of four stable isotopes (of which one may in the future be found radioactive), and one very long-lived radioisotope (96 Zr), a primordial nuclide that decays via double beta decay with an observed half-life of 2.0×10 19 years; [4] it can also undergo single beta decay, which is not yet observed, but the theoretically predicted value of t 1/2 ...
