Question

Why the valency of chlorine is 1 in hydrogen chloride?

Answer 1

Answer:

For element, if the number of electron is greater than or equal to 4 then the valency will be the number of electrons present in the outer shell. If no. of electron is less than 4 then valency will be (8-n) where n is the number of electrons in the outer most shell. Valency = (8-7=1). So valency of chlorine is 1..
