雙語使用場景

That's what we call when we have three bonding atoms and one lone pair.───這是當我們有3個成鍵電子，和一個孤對時這樣稱它。

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？

The lone-pair interactions change the chemical characteristics of the carbon.───這些孤對電子相互作用，改變了碳原子的化學性質。

A lone pair of watchful eyes───一雙注視的眼睛

英語使用場景

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.
