Abstract:
As is well known the year 2019 as the International Year of the Periodic System Table was declared. Moreover, there are 150 years from the Mendeleev’s formulation of the Periodic System, Periodic Table or Law. In the year (2016), in addition, the rest of the all known 118 elements with their names and symbols were defined. Also with the quantum mechanics’ postulates and principles, the physical and chemical properties of the elements, which vary periodically by their atomic structure, with their place in the Periodic Table were related. It looks like that all questions concerning Periodic Table are solved, with the exception of some, so told, unimportant or no so relevant things. Besides this small number of exceptions, one big the most important thing, regarding the relationship between Quantum Mechanics and Periodic Table's shape is excluded, and ignored from the scientific community for nearly 100 years, or from the of the quantum mechanics birth. This is the duality of all rows (periods) in the Periodic Table. Each of these doubled periods is with the same “spd or f” structure and these doubled periods were named as Dyads (French – Dyades). This new possibility in the Periodic Table on the reflection or the mirror symmetry is based. This information is so important that will change the qualification of the main or principal quantum number if it, in the new modified quantum number’s set will be applied.
