An O2− ion moves from a region where its electric potential energy is 12.0 × 10−18 J to one where its electrical potential energy is 7.6 × 10−18 J. Use e = 1.602 × 10−19 C. a. What is the change in potential energy?
b. What is the change in electrical potential (i. e. “voltage”)?

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?
