那么我们有多少孤对电子呢？
那么，哪个原子需要这对孤对电子呢？
孤对电子对键能的影响不是原子间的效应。
The influence of lone pair on bond energy cannot be an interatomic effect.
这些孤对电子相互作用，改变了碳原子的化学性质。
The lone-pair interactions change the chemical characteristics of the carbon.
因此我们需要将这两个剩下的价电子,作为孤对电子加到我们的结构中。
So we need to add those 2 valence electrons left as lone pair electrons in our structure.
本文通过对孤对电子效应的研究来阐明孤对电子在分子结构和化学反应上的重要性。
In this paper, importance of the lone pair electrons in molecular structure and chemical reaction is expounded by effect of the lone pair electrons.
探讨了孤对电子对于缺陷态化学键的影响，证实了孤对电子在硫属玻璃中的重要作用。
The effect of lone-pair electrons on bonding in defect states is also discussed and it is shown that they play a significant role in chalcogenide glasses.
氮原子孤对电子与氮氮键以及氮氮键相互之间的超共轭作用是影响氮氮键长的重要因素。
The hyperconjugation between lone-pair of nitrogen atoms and nitrogen-nitrogen bonds, or among nitrogen-nitrogen bonds play a significant role on the nitrogen-nitrogen bond length.
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。
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.
好吧，我们这里讨论的是一个挺大的数，为了数起来更容易，我们就说有十对孤对电子，因为二十个跟十对是一个意思。
Well, we're talking about a pretty high number here, so to make counting easier, we'll just say 10 lone pairs, because 20 lone pair electrons is the same thing as 10 lone pairs.
如果我们想算出碳原子的形式电荷，我们需要将价电子的个数，也就是四，减去孤对电子的个数，它是多少？是二。
So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.
胺上的氮原子存在着一种电子对，化学家们管这叫孤对电子（译者：嘿嘿~高中知识竟然还未忘记），而正是这些孤对电子把胺分子牢牢绑在纳米管上。
The nitrogen atoms of amines have what chemists call a lone pair of electrons, and it is this which attaches each amine molecule to the nanotube.
这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。
So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
