However, periodic tables of three or more dimensions have the potential to include additional properties, such as electronegativity, ionization energy, electron affinity, or physical properties like boiling point or melting point. This expanded information can offer a more complete picture of the elements and their characteristics.
The construction of the periodic table ignores these irregularities and is based on ideal electron configurations. [ 2 ] Note the non-linear shell ordering, which comes about due to the different energies of smaller and larger shells.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.

118 chemical elements have been identified and named officially by IUPAC.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).
A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. [1] The term seems to have been first used by Charles Janet. [2] Each block is named after its characteristic orbital: s-block , p-block , d-block , f-block and g-block .
It aims to categorise all three-, four- and five-dimensional shapes into a single table, analogous to the periodic table of chemical elements. It is meant to hold the equations that describe each shape and, through this, mathematicians and other scientists expect to develop a better understanding of the shapes’ geometric properties and relations.
