So, this is the chloride ion. It's over here. 這是氯離子，把它放這兒。
So now, let's get a sodium here, and the chloride ion next to it to the point where they are touching. 所以，我們要有一個(gè)鈉離子，和氯離子放在,相互接觸的一個(gè)點(diǎn)上。
So, for example, if I have a sodium ion over here, and I have a chloride ion over here, where the distance from center to center r I'm denoting as r, this is nucleus to nucleus separation. 所以，比如這有一個(gè)鈉離子，和一個(gè)氯離子，它們中心與中心間的距離,我把它設(shè)爲(wèi)，這是原子核和原子和的間距。

We talked about this reaction here where we had chloride ion in the gas phase plus sodium ion in the gas phase. 我們?cè)谟懻撨@一個(gè)反應(yīng),我們有氣相的氯原子,與氣相的鈉原子接觸。 麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選
We started with gaseous sodium to make gaseous sodium ion and gaseous atomic chlorine to make gaseous chloride ion through electron transfer. 我們從氣態(tài)的鈉開始,得到氣態(tài)的鈉離子,從氣態(tài)的氯原子,通過電子轉(zhuǎn)移得到氯離子。 麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選
