How is valency of atom related to its electronic configration... |
| Answer» Valency is the combining capacity of an atom. Valency is calculated by using number of valence electrons present in an atom. The number of electrons present in the last shell of an atom and take part in chemical bond formation are known as valence electrons.The number of electrons which an atom has in its last orbit can be found out by writing the electronic configuration of an atom. So, electronic configuration expresses the valence electrons which are related to the valency of an atom. | |
