Question

how does the electronic configuration of the atom of an element relate to its position in the modern 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.

To know its position in periodic table first we should know the electronic configuration of the element. Valence electrons: The electrons, which are present in the outermost shell of an atom are called valence electrons. ... For any element the valence shell number is equal to its period number.

The number of valence electrons decides an atom’s position in the periodic table while the electronic configuration decides the number of valence electrons.
