“…In the early years of the 17 th century, when new isotopes of many elements were discovered and about only 60 elements were known, Robert Boyle in 1661 proved that elements are formed by atoms. Building on the element's properties, Johann Wolfgang Dobereiner achieved in 1829 a form of arrangement to the known elements into families or Triads, and in 1865 a new step came by John Newlands who noticed that element properties were more similar to the following element, which was named the Octaves, unfortunately there was not a suitable patterns to fit with Newlands, and this step was rejected as it was not fitting with the attitude of British chemical society [1][2][3][4][5][6].…”

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, and recurring chemical properties, whose structure shows periodic trends. However, the current periodic table shows a gaps and separated groups of elements in which the f-block elements of Lanthanides and Actinides are split. Keeping the current the atomic number arrangements of groups and periods, this research has proposed new method of elements arrangement, in which the separated f-block elements of Lanthanum, (Lanthanides & Actinides) were emphasized to their proper position in the table rather than remaining exiled. This new Method of elements arrangement proposed in this research to fit with periodic system of elements in the IUPAC's Periodic Table. The main outcome is to introduce layout regularity, which may reflect the regularity of the periodic law more faithfully. In this research, elements are placed at groups and periods according to atomic numbers which were horizontally displayed into 7 Periods and 12Groups vertically, this displays in addition to 20 horizontal coordination (named as Nada involved in this study) to determine and dispense altogether the elements positions at the periodic system, determining and dispensing altogether the elements positions at this 3D-modified periodic table. Application of this 3D-modified table helps to determine the atomic number to any element at any part at the main body of the periodic table. In addition, the relationship of f-block elements to the other blocks of the periodic table also becomes easier to see. In addition, this method extensible to expand future table and determining the atomic number and positions of the 55 future elements starting from 119 till the element of 136, at the main body of the IUPAC's Periodic Table.

The periodic depictions of the natural system of elements produced by Mendeleyev and his contemporaries were based on atomic mass A and chemical valence G of the elements then already discovered. In their and in later more refined periodic tables the periodicity was initially highlighted for values of G from 0 to 8; but long tables with 18 groups were soon required to account for the growing number of elements and their chemical properties. The atomic masses (co-determined by the assorted isotopes of an element) were replaced by the atomic number Z. The current knowledge of the electronic states of atoms and molecules now calls for a standard form of the periodic table which reflects the large energy gaps between the noble-gas (sp) 8 core shells and the electronic open spdf valence shells, which physically determine the chemical periodicity of rows with lengths increasing in double-steps. A graphic representation as introduced in IUPAC's Red Book has served well for education and research in chemistry. There is presently no need for graphical or other changes, but existing "irregularities" of single atoms or groups of atoms, mainly those of higher values of Z, require dedicated considerations based on the laws of physics which allow to rationalize unexpected deviations from the Aufbau principle and other rules-of-thumb.
