We talked about this reaction here where we had chloride ion in the gas phase plus sodium ion in the gas phase.

我们在讨论这一个反应,我们有气相的氯原子,与气相的钠原子接触。

Now in this particular reaction, I've got hydrogen gas, iron solid. Those already are elements in their most stable forms at room temperature and pressure.

特定的反应中，我有氢气,固态铁，这些都已经是,处于室温和常压下,最稳定的元素单质。

And, this is a really clever reaction because titanium tetrachloride is a gas.

这是一个非常巧妙的反应,因为四氯化钛是一种气体。

So we are really looking at this reaction here H+ for ionization. It is H gas neutral goes to H plus in the gas phase plus the electron. And, furthermore, we can have multiple ionization energies.

所以我们真正看到的是,电离，它是在气相中H变为,和电子的过程，还有，我们能电离能加倍。
