-
Coulomb's law still works.
-
What was wrong was the way they treated kinetic energy,
-
because kinetic energy quantum mechanics reformulates.
-
So it gives you electron clouds.
-
And so what's a cloud is not the positive charge --
-
remember, J.J. Thomson had a positive sphere of electricity
-
in which he embedded the electrons -- what's a cloud is the electrons,
-
and nuclei are put in it, to make molecules.
-
So it really is -- he was right about plum-puddings,
-
he just had the charges backwards.
-
Not many people give him credit for that.

So cubic octets of Lewis and ad hoc electrostatic force laws,
