1·So how many lone pair electrons do we have?

那么我们有多少孤对电子呢？

2·So, which atom is in need of those lone pair electrons?

那么，哪个原子需要这对孤对电子呢？

3·That's what we call when we have three bonding atoms and one lone pair.

这是当我们有3个成键电子，和一个孤对时这样称它。

4·The influence of lone pair on bond energy cannot be an interatomic effect.

孤对电子对键能的影响不是原子间的效应。

5·So we need to add those 2 valence electrons left as lone pair electrons in our structure.

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。

6·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.

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。

7·In this paper, importance of the lone pair electrons in molecular structure and chemical reaction is expounded by effect of the lone pair electrons.

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。

8·But a lone pair ofgnarled mulberry trees planted by the Armenians were all Mr Bayram had—untilthe European Union rode to the rescue with a big grant.

在欧盟的巨额援助拨款下来之前，Bayram先生所拥有的只是2棵亚美尼亚人留下的老桑树。

9·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。

10·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.

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。
