    Are you refering to the total number of valence electrons? And is it CN or CN- that you want this for?

    Show us what you tried. How did you get the number 9?

    Perhaps the easiest way to figure this out, is to look at both of that atom's group numbers. This will tell you the number for valence electrons. For a molecule, just add those numbers.
