Valency of chlorine: By using this method

By using this method, you can find the valency of chlorine, sulfur, magnesium, and more. This helps us understand their chemical properties and how they behave. Figuring out the valency of elements like chlorine, sulfur, and magnesium is easier with the electronic configuration method. Learn about the valency of Chlorine and how it's determined by its electron configuration. Understand why the typical valency of Chlorine is 1. Since the atom has 2 valence ... Since chlorine has 7 electrons in its valence shell, and chlorine needs just one more electron to complete its octet, it exhibits a valency of 1, as it tends to gain one electron during chemical reactions. The electronic configuration of chlorine can be expressed as 1s2 2s2 2p6 3s2 3p5 Alternatively, using noble gas notation, it can be ...
