Question

how electronic configuration of atom does relate it's position on periodic table. ​

Answer 1

Answer:

The electronic configuration of an atom relates to its position in the modern periodic table as when we arrange the electrons in the 1st , 2nd , 3rd and 4th shells i.e. ... So, its' electronic configuration is 2,8,1 and its valency is +1 . This element therefore comes in Group 1 with +1 valency.

Answer 2

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.

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.
