How many electrons are missing from each ion?

When two identical ions are separated by a distance of 6.2 x 10^−10 m, the electrostatic force each exerts on the other is 5.4 x 10^−9 N.

    F = k*Q*q / d²

    and here Q = q = n*e

    where n is an integer

    and e is the elemental charge = 1.6e-19 C

    5.4e-9 N = 8.99e9N·m²/C² * (n*1.6e-19C)² / (6.2e-10m)²

    n = 3 (electrons)

    Hope this helps!
