In its compounds, Zn 2+ ions have an electronic configuration [Ar] 3d 10.As such, Zn 2+ tends to have a symmetrical coordination geometry in both its complexes and compounds. In both ZnO and ZnS, zinc is bound tetrahedrally bound to four ligands (oxide and sulfide, respectively).
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers.

The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
[25] [137] Another alloy, marketed under the brand name Prestal, contains 78% zinc and 22% aluminium, and is reported to be nearly as strong as steel but as malleable as plastic. [ 25 ] [ 138 ] This superplasticity of the alloy allows it to be molded using die casts made of ceramics and cement.
The name of the metal was first documented in the 16th century, [40] [41] and is probably derived from the German zinke for the needle-like appearance of metallic crystals. [42] Alchemical symbol for the element zinc. The isolation of metallic zinc in the West may have been achieved independently by several people in the 17th century. [43]
