During a chem lesson my professor was demonstrating Coulomb's law using HCl.
Fe = kq1q2/r^2
so what he did was he replaced q1 and q2 with 0.17 and -0.17.
Then he showed an example with LiF and then replaced q1 and a2 with 1 and -1.
I think he was trying to show us how strong ionic bonds were. Can someone please explain why and how the numbers 0.17 and -0.17 were chosen for HCl and 1 and -1 were chosen for LiF?
