雙語使用場景

So, which atom is in need of those lone pair electrons?───那么，哪個原子需要這對孤對電子呢？

So how many lone pair electrons do we have?───那么我們有多少孤對電子呢？

So we need to add those 2 valence electrons left as lone pair electrons in our structure.───因此我們需要將這兩個剩下的價電子,作為孤對電子加到我們的結構中。

英語使用場景

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.

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.

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

So in terms of nitrogen that starts off with a valence number of 5, again we have 2 lone pair electrons in the nitrogen, and again, we have 6 electrons that are shared.

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

So in oxygen we have a similar situation where, in fact, we are not going to promote any of the electrons because we have two lone pair electrons no matter what we do.

So how many lone pair electrons do we have?

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.

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.
