electrostatic charge between a na+ ion and a cl- ion

I have the relevant equation, I just need to know the charges (in coloumbs) of the two ions so I can plug them into it. I thought that it would just be the equivalent charge of the one spare proton/electron, but that did not work so I guess it was a faulty assumption. I have not been able to find this information anywhere.

Cl- means one extra negative elementary (electron) charge. Na+ is one extra positive elementary charge.

Thats what I thought, but when I plug the values for those into the equation, it comes out with an answer that is off by a factor of 10 decimal places.
