There's a compound NaX. You're trying to determine what element X is,
but all you know is that the difference (subtraction) in electronegativity
values of X and Na = 3.1.
You look at Reference Table S and find the electronegativity value of Na is
0.9. Based on this information, which element below has to be element
X to get the subtracted difference in electronegativities to be 3.1?
F
Br
I
CI
