ABSTRACT
When the elements were represented by the order of their atomic weights, their properties were repeated in a series of periodic intervals, Periodic Table of the Elements (PTE). Since the discovery of the atomic number, the true independent variable of PL, PTE is redefined. When the elements were represented by the order of their atomic numbers, their properties were repeated in a series of periodic intervals, PTE. Scientists work over the years revealed much about the atoms, which are matter building blocks, which make up the elements. Scientists of the 19th century discovered more than 50 different atoms, everyone with its own mysterious properties. The basic structure of PTE emerges from the universal and fundamental laws of quantum mechanics. Every chemical element is defined by its atomic number, which is an integer. Some periodic properties are atomic weight, density, atomic radius, crystal structure, order of incorporation of the electrons, atomic emission spectrum, matter aggregation states, etc.
