How can we calculate the valency of elements ??
Asked by Jitendra | 3rd Nov, 2017, 06:27: PM
Valency of an atom is equal to the number of electrons in the outer shell.
If the number of electrons in the outermost shell is four or less than four then it is the valency of that atom. Otherwise the valency is eight minus the number of electrons in the outermost shell.
If you know the number of electrons in the outer shell then you can calculate the valency.
