A fluorine atom has 9 electrons - 7 in its outer shell and 2 in its inner shell. How many electrons would be in the outer shell if it were to become a fluoride ion?
You are spending the summer working for a chemical company. Your boss has asked you to determine where a chlorine ion of effective charge -e would situate itself near a carbon dioxide ion. The carbon dioxide ion is composed of 2 oxygen ions each with an effective charge -2e and a carbon ion with an effective charge +3e. These ions are arranged in a line with the carbon ion sandwiched midway between the two oxygen ions. The distance between each oxygen ion and the carbon ion is 3.0 x 10-11 m. Assuming that the chlorine ion is on a line that is perpendicular to the axis of the carbon dioxide ion and that the line goes through the carbon ion, what is the equilibrium distance for the chlorine ion relative to the carbon ion on this line? For simplicity, you assume that the carbon dioxide ion does not deform in the presence of the chlorine ion. Looking in your trusty physics textbook, you find the charge of the electron is 1.60 x 10-19 C.
8. Of the following, which is most likely to become a cation as a result of a chemical reaction?
What would be the charge on that cation?
a) N; -3
b) Ne; +1
c) Na; +1
d) I don't know how to make this type of prediction. Aren't there too many variables to tell?

And this is the picture I have to use for this quetion. Everyone keeps drawing a different diagram to fit in the 15 electrons. I'm so confused about this. I believe the molecular electron configuration is: (σ2s)2(σ*2s)2(π2p)2(π2p)2(σ2p)2(π*2p)1 Correct? That is 11, so I'm not sure why I keep getting different answers about this. Can you please help?
