How it can be proved that the basic structure of the Modern Periodic Table is based on
the electronic configurationof atoms of different elements?

Explanation

Modern periodic law states that the physical and chemical properties of an element in the
periodic table are the periodic function of the atomic number of that element. Electronic
configuration of the elements plays an important role in the placement of elements in the
modern periodic table. The valence shell electrons of an element decide its position in a
particular group or period.
Thus, the modern periodic table is based on the electronic configuration of the different elements.
