Significant Physical/Chemical Change Found by Sign Reversal?

  • #1

Main Question or Discussion Point

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.

We know that "plastic" and "glass" charges were arbitrarily assigned...
If you know that the choice was arbitrary, what significant physical or chemical changes do you expect?
