When two identical ions are separated by a distance of 4.0×10^−10 , the electrostatic force each exerts on the other is 5.7×10^−9 .

How many electrons are missing from each ion?

what i did was used coulombs law to find the value of q1 and q2 , so q1+q2=1.013333333^-37

Now would i divide that by 4 since the number of + and - charges are suppose to add up to that number and also there are 2 ions??
