Explanation:
Valency is the number of electrons that an atom gains, loses or even shares during a chemical reaction. The valency of noble gases is zero because their outermost energy level is completely filled with electrons [ have 8 electrons except (He) has 2 electrons]. The valency of an element is determined according to the number of electrons in the outermost energy level of its atom.
