The valency of Metal M is 2 Let us find the valency of chlorine Chlorine has 7 valence electrons, so its valency is = 8-7 = 1 Here the metal M combines with two chlorine atoms means its combining capacity or valency is =2 Valency The combining capacity of the atoms to form molecules either with same or different elements is defined as valency. Atom contains less than four electrons in its outermost shell, the valency of an atom is equal to the number of electrons present in the valence shell. Example: Sodium has one electron in its outermost shell, so the valency of sodium is 1. so it can bind to 1 chlorine atom Calcium has two electrons in its outermost shell, so the valency of calcium is 2. So it can combine with two chlorine atoms. Aluminum has three electrons in its outermost shell, so the valency of aluminum is 3. If the outer shell has more than four electrons, the valency = 8 - the number of electrons in the outer shell. For example oxygen has 6 valence electrons ,the valency of oxygen = 8 - 6 = 2
