Notation confusion

    1. The problem statement, all variables and given/known data
    Hi guys, I am having a issue with the notation of this question. I can workout what to do, but I don’t understand what is $$C^+,C^{++}$$
    Could someone please explain. My thought is maybe is 2 carbon atoms bonded together?
    2. Relevant equations

    3. The attempt at a solution

    C++ is doubly ionized, a carbon atom which has lost two electrons, and so has net 2 positive charges. This notation continues with numbers like C3+.
