The potential energy of a charge Q1 in the presence of another charge Q2 can be expressed in terms of the Coulomb potential, φ(phi): The units of potential are joules per coulomb, J C−1, so when φ is multiplied by a charge in coulombs, the result is in joules. The combination joules per coulomb occurs widely and is called a volt (V), with 1 V = 1 J C−1. Calculate the Coulomb potential due to the nuclei at a point in a LiH molecule located 200 pm from the Li nucleus and 150 pm from the H nucleus. (Hint: Use Q = +Ze, where Z is the atomic number and e is the elementary charge.)
