双语场合用语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。

英语场合用语Wigeon A lone pair of gad wall preened on shrinking tussocks.
So, which atom is in need of those lone pair electrons?
And if we put that in our bond here, we have 1, 2, 3 bonds, plus we have one lone pair left over.
So in oxygen we have a similar situation where, in fact[sentencedict.com], we are not going to promote any of the electrons because we have two lone pair electrons no matter what we do.
For the carbon, we start with 4 valence electrons, we have 0 lone pair electrons minus 4, and we end up with a formal charge of 0.
In this paper(http://sentencedict.com), importance of the lone pair electrons in molecular structure and chemical reaction is expounded by effect of the lone pair electrons.
So how many lone pair electrons do we have?
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.
For the first time the significance of lone pairs of electrons, in determining the overall shape of molecules was recognised.
