Is it that when chlorine is combining we take its valency to be one and when the chlorine is singular we take it valency to be 2? Eg: Valency one: BaCl2 (Barium Chloride) Valency two: 2AgCl---> 2Ag Cl2 Can anyone please clarify my doubt here from Class 10 Chapter 1 Science Chemical Reactions and Equations. I came across this doubt in this question H2 Cl2 = HCl When we are supposed to balance the equation. I have a doubt why it is written as Cl2 when valency is 1. ​?

Valency of Chlorine

The valency of an element is the combining capacity of the element with other elements. Chlorine is a halogen and has a valency of 1. This means that it can combine with other elements by sharing one electron to form a single bond.

Valency of Chlorine in Compounds

When chlorine combines with other elements to form a compound, its valency is still 1. For example, in Barium Chloride (BaCl2), chlorine combines with Barium to form a compound by sharing one electron with Barium. In this compound, there are two Chlorine atoms, each with a valency of 1.

Valency of Chlorine in Diatomic Molecules

Chlorine is a diatomic molecule, which means that it exists in nature as a molecule with two chlorine atoms. In this case, each chlorine atom still has a valency of 1. However, when writing the formula for a diatomic molecule, we use the subscript 2. For example, the formula for Chlorine gas is Cl2, which means that there are two Chlorine atoms in the molecule.

Balancing Chemical Equations

When balancing a chemical equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. In the equation H2 + Cl2 = 2HCl, we have two Chlorine atoms on the left side of the equation and two Chlorine atoms on the right side of the equation. The subscript 2 in Cl2 indicates that there are two Chlorine atoms in the molecule.

In conclusion, the valency of Chlorine is 1 whether it is in a compound or a diatomic molecule. The subscript 2 in Cl2 indicates that there are two Chlorine atoms in the molecule, and it is used when writing the formula for a diatomic molecule.
