4. The diagram shown in right indicates the distances between the nuclei, pA and pB, and the electrons, e₁ and e₂, in a hydrogen molecule. What is the electrostatic potential energy the electrostatic potential energy of this molecule that we would expect?

所以這題你要記得兩個點電荷靜電位能的公式

有4個粒子,兩兩配對所以總共有4*3/2=6種
然後根據公式你可以知道兩兩同號、正向所以位能為正
兩兩異號,反向所以位能為負
所以正的向分別是pa、pb,e1和e2
負的向是pae2、pae1、pbe1、pbe2
然後就列位能式
質子帶+e、電子帶-e
