Question

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

Answer 1

Answer:

Check the explanation

Explanation:

The electronic configuration of an atom helps us to predict the position of the atom in the periodic table.                                                            

(i) The number of the outermost shell corresponds to the period. For example, if the periodic table. second outermost shell, it belongs to second period and so on.                    

(ii) The number of electrons in the outermost shell corresponds to group in the periodic table.

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.

Answer 2

Answer:

Hii sis do u like my dp tell me in my questions

The electronic configuration of an element is related to its position on the periodic table. The links are: ... the number of electrons in all shells of an element is represented in the periodic table as the element's atomic number.
