MediumWhat is the main basis for the arrangement of elements in the modern periodic table? Describe it.
(N/A) The main basis for the arrangement of elements in the modern periodic table is the electronic configuration of the elements.
According to the modern periodic law,the physical and chemical properties of elements are a periodic function of their atomic numbers $(Z)$.
This means that elements are arranged in increasing order of their atomic numbers,which reflects their electronic configuration,leading to the repetition of similar properties at regular intervals.
