# 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!
