Question

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

Answer 1

$\red{\bold{\underline{\underline{Answer}}}}$

When elements are arranged according to increasing atomic numbers, there is a periodicity in the electronic configurations of the elements. The elements in a period have consecutive atomic numbers. The elements having same number of valence electrons in their atoms are placed in a group. All the elements in a group have similar electronic configurations and show similar properties.

Answer 2

Answer:

modern periodic table is divided into five blocks s ( s,p,d,f) and after electronic configuration the last atom lies in that block is called that it is the element of that block .
