A sodium ion $(N{a}^{+})$has one more proton than electron. A chlorine ion $(($:$C{l}^{-}\}$has one more electron than proton. In solution, a sodium atom is $5\mathrm{.}0nm("$nano$,n^{\text{'}\text{'}}={10}^{-9}$ in SI$)$ away from a Chlorine atom. What is the magnitude of the electric force from the chlorine atom on the sodium atom? Is the force attractive or repulsive?
