Question

How does the electronic configuration of an atom relate to its position in the modern periodic table?​

Answer 1

Answer ⤵️

Electronic configuration of an element gives the information of valence electrons and number of shell present in the element. We get the information of group number after knowing valence electrons.

The number of shells present in an element is equal to the period number. Thus, by knowing electronic configuration we know the group number and period number of an element, and the position of an element in the periodic table.
