WebThe change in energy is simply the potential energy created by interactions between the +1 charge and the charges in the molecule. We can calculate this energy by calculating (+1)(q molecule)/r for each charge in the molecule, q molecule, and adding up all of these energies. This energy is the molecule’s electrostatic potential. WebFor a single electron, the charge (q) is the elementary charge (ee). The following derives to the exact value and units of the electron’s mass when using electrical properties ( … WebThe charge moved is related to voltage and energy through the equation ΔPE = q Δ V.
