Octet and Duet Rule

  1. Feb 17, 2009 #1
    1. The problem statement, all variables and given/known data

    Using your knowledge of the octet rule and the duet rule, determine the missing subscript (??) for the compound below.


    What is a good way of solving this type of equation and what is the answer. I figure you need to draw a Lewis dot structure but knowing what else is need i don't know.
