Are Gram negative bacteria classified as such because of their negative membrane potential?

Does the membrane potential usually quoted for Gram negative bacteria (*e.g.*, *E. coli*) refer to the potential across both membranes? - If yes, then does the potential fall more over the inner or outer membrane? Are there any studies that estimate/measure the relative fraction for each membrane?I assume that the measurements of potential are usually carried out by inserting an electrode inside the cell and measuring the difference with the outside, this would make the answer to the first question yes.
