Question

How to divide elements into groups and periods of the periodic table using electronic configuration? ​

Answer 1

Answer:

The electronic configuration of an atom is the numerical representation of the arrangement of electrons distributed in the orbitals of the atom. This determines the position of an element in the periodic table and in turn its chemical behavior. It explains how the atoms are held together by the chemical bonds, and the peculiar trends which are observed in the rows and columns of the periodic table. In this article, we will discuss the electronic configuration of elements in the same periods and groups of the periodic table.

Answer 2

Explanation:

electronic configuration of any element tell about ist group and period

for example

1s2 here 1 represents its period and s represents its its block and 2 represents no of electrons in that orbital

by knowing this we can also identify the gropus of that elements by seeing its last orbitals electronic confighration for example helium and neon
