LP—孤电子对(Lone Pair electron) BP — 成键电子对 ( Bond Pair electron ) 叁键>双键>单键. ⑶分子的几何构型主要决定于中心原子的价层电子对的数目和类型(LP或BP).

Yeah, so also 4. We started with 10 valence electrons, we used up 6 of those as bonding electrons, so we have 4 left, which will be lone pair electrons.
对,也是四个,我们从十个价电子开始,只用了六个来成键,因此我们还剩下四个,它们将成为孤对电子。
And we give different names, depending on what kind of electrons we're dealing with, so, for example, with h c l here, we can talk about having bonded versus lone pair electrons.
我们还起了不同的名字,给我们要处理的不同类型的电子,以氯化氢为例,我们来介绍一下成键电子与孤对电子。
We see three bonding pairs so this is a triple bond, indeed a multiple bond.
我们看到3对成键电子所以这是一个三重键,它确实是多重键。
