So if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.

如果我告诉大家单个氢原子的能量，是负的，1312，千焦每摩尔。

If we want to talk about two hydrogen atoms, then we just need to double that, so that's going to be negative 2 6 2 4 kilojoules per mole that we're talking about in terms of a single hydrogen atom.

而要讨论两个氢原子，我们只需要把它乘以二，因此应该是负的，2624，千焦每摩尔，这就是单个的氢原子的情况。
