. How do you calculate the possible valency of an elements from the electronic configuration of its atoms


Best Answer

Ans. The valency of an element is determined by the number of valence electrons present in the atom of the elements. Electronic configuration gives the number of valence eletrons in its. The number of valence electrons decides the number of electrons lost or gained by one atom of an elements to achieve the nearest inert gas electron configuration and gives the valency of elements
