The potential energy of a charge (Q1) in the presence of another charge (Q2) can be expressed in terms of the Coulomb potential (phi) V = Q1 · ¢ Q2 $ = The units of potential are joules per Coulomb, so when phi is multiplied by a charge in Coulombs, the result is in joules. The combination joules per Coulomb occurs widely, and was therefore given it own name: a volt (V). Calculate the Coulomb potential due to the nuclei at a point in a LiH molecule located 200pm from the Li nucleus and 150pm from the H nucleus. Hint: Use Q=+Ze, where Z is the atomic number and e is the elementary charge. (ans: 31.2 V)
