Asked by Rucha
What is the effective nuclear charge of the following?
F-
Na+
I know that for F- it is 9-7=2
and for Na+ it is 11-2=9, but what about the charges??
I don't understand what effect do the charges make?
If 9-7 then isn't it just simply F and not F-? Similarly, if 11-2 then isn't it just simply Na and not Na+??

I think you are confused with the definition. Here is a site that gives you the effective nuclear charge for Na^+ and F^-.
Zeff = #protons -#inner electrons = ?
For Na^+ that is 11-2 = 9+.
For F^- that is 9- 2 = 7+.
