Homework Statement
"Calculate the force of attraction between a K +
and an O 2- ion whose centers are separated
by a distance of 1.5 nm."
Homework Equations
F = [ k (Z1)(Z2) ] / r^2
The Attempt at a Solution
Both valences are filled when K is a + charge and O is a 2- charge. My main problem is I don't know what to use for "Z". I would just use 1 and -2, but the shells are filled and maybe there isn't much attraction at all?
Any help is greatly appreciated, thanks!
