    welcome to pf!

    hi soccerballboy! welcome to pf! :wink:
    ok, so how many atoms are there in the ring?

    and how much charge in each atom? :smile:

    There are 3 electrons in the outer orbital? and there is -1.6 x 10^-19 C Negative charge in each electron? So do I just multiply those two together?

    Does that sound correct?

    isn't it asking for the charge of all the electrons (ie not just the outer ones)?

    (and, separately, all the protons)
