Zinc has an electron configuration of [Ar]3d 10 4s 2 and is a member of the group 12 of the periodic table. It is a moderately reactive metal and strong reducing agent. [48] The surface of the pure metal tarnishes quickly, eventually forming a protective passivating layer of the basic zinc carbonate, Zn 5 (OH) 6 (CO 3)
Group 12, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd), mercury (Hg), [2] [3] [4] and copernicium (Cn). [5] Formerly this group was named IIB (pronounced as "group two B", as the "II" is a Roman numeral) by CAS and old IUPAC system. [note 1]
All this can vary across the values (data rows). So depending on the row and the specific value, additional formattings may be added by the template (e.g., a newline <br/>) Central data values. Some data, like standard atomic weight, are read from a central list. This way, enwiki has the same values everywhere.
Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms.

Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
According to data from the US Department of Agriculture, however, over two billion people — about 40% of the world’s population — are zinc-deficient. Symptoms of zinc-deficiency can include ...
