This research has proposed formulas, in which the atomic number and neutron numbers to any element in the periodic table are determined according to element position in the periodic table. These formulas have been arranged 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, atomic number to any element in the periodic table is predictably calculated by the group and period numbers which were displayed into 7 Periods horizontally, and 18 Groups vertically, determining and dispensing altogether the elements positions at the periodic system. Application of these proposed formulas showed linearity from has good agreement with these separated elements of Lanthanum in the f-block elements (Lanthanides and Actinides), which were in no interruptions in the sequence of increasing atomic numbers. In addition, the relationship of the f-block to the other blocks of the periodic table also becomes easier to see. In addition, the formulas are extensible to expanding future table and allowed determining the atomic number of the future elements starting from 119 till the element of 136, at the main body of the periodic table, and can be used as a simple and alternative method for determine the numbers of atomic and neutron in the IUPAC's Periodic Table.
