But we've defined the enthalpy of those elements in their stable state at room temperature and pressure as zero, right?
但我们已经定义了这些,元素处于它们室温和常压下,最稳定的状态时的焓为零，对吧？

Hydrogen gas it's in its most stable state, right at room temperature and pressure.
和常压下氢气是氢元素，最稳定的状态，这个小“0“

It then made Massachusetts the most stable state or essentially the most stable state in the country and it was widely-admired.
那时，它使马萨诸塞州成为了美国最稳定的州,或者说本质上最稳定的州,并广受好评与赞赏。

So, what we know is happening is that were having transitions from some excited states to a more relaxed lower, more stable state in the hydrogen atom.
我们知道，这里所发生的是,氢原子从激发态到更低更稳定的态的跃迁，而我们用眼睛可以探测到的。
-
Delta H of formation means the enthalpy of this compound minus the enthalpy of its constituent elements in their most stable state at room temperature and pressure.
生成焓就是这种组分,的焓减去它的所有组成元素,在室温和常压下处于,其最稳定的状态时的焓。

So, if we want to go from that stable state to that less stable state, we need to put in a certain amount of energy to our system, that difference between the free electron and the electron bound to the metal.
所以，如果我们想使电子,从稳态到达不够稳定的状态，我们需要引入一定数量的,能量到系统中，即自由电子和束缚于金属的,电子的能量差。
