What is the formula of valency?
Formula of valency Write the electronic configuration of an element. 2. If the outermost shell has less than or equal to four electrons then the valency is the number of outermost electrons. 3. If the outermost shell has more than four electrons then the valency is 8-(the number of outermost electrons).
