So what we can actually directly compare is the dissociation energy or the bond strength of nitrogen versus hydrogen.

因此实际上我们可以直接进行比较,对氮分子与氢分子的离解能,或键的强度。

In contrast, the dissociation energy of a bond for hydrogen, and molecular hydrogen is everywhere around us, we see 432 kilojoules per mole.

相反，氢分子在我们周围到处都是，一个氢分子的离解能，是432千焦每摩尔。

So, let's change our graph where we now have this zero point set as the two individuals hydrogen atoms, and then we see that our h 2 molecule is at the negative of the dissociation energy, or the negative what that bond strength is.

那么让我们把曲线图中的零点能改到,两个分离的氢原子处，那我们就会看到,氢分子就是负的离解能，或者负的键的强度。
