Significant Physical/Chemical Change Found by Sign Reversal?

Click For Summary
SUMMARY

The discussion centers on the arbitrary assignment of charges to materials such as "plastic" and "glass," designated as negative and positive, respectively. According to Randall D. Knight in "Physics for Scientists and Engineers," this assignment does not lead to significant physical or chemical changes in calculations if protons are considered negative and electrons positive. The consensus is that the only outcome of such a reversal would be the generation of negative numbers in calculations, with no substantial impact on the underlying physics.

We know that "plastic" and "glass" charges were arbitrarily assigned to be negative and positive respectively, and electrons and protons were given their charges based upon that assignment (According to Randall D. Knight in Physics for Scientists and Engineers). I am curious if any significant physical or chemical changes would occur in calculations if we considered protons to be negative and electrons positive. Or would the only difference be simply yielding negative numbers in calculation?

No significant difference. The selection of sign was purely arbitrary.

If you know that the choice was arbitrary, what significant physical or chemical changes do you expect?
