Two shared valence electrons forming a bond between adjacent nuclei.───形成电子核子之间的键的两个共享原子价电子.

What if we capture all of the valence electrons?───如果我们捕获了所有价电子会怎样呢？

So we have seven valence electrons.───我们有七个价电子。

Now with this framework, I said that talking about these valence electrons might give us some insight into chemical reactivity.───现在在这个结构下，我说过讨论这些价电子可能会让我们对化学反应有更深的理解。

This a chemical bond that results from the sharing of valence electrons between atoms.───一种是共价键,是由原子间共享价电子形成.

The outer ring contains the valence electrons.───排在外层的有价电子.

In molecules with unpaired valence electrons, spin-spin coupling between valence and core electrons leads to further small splittings.

Two shared valence electrons forming a bond between adjacent nuclei.

Bonding may be ionic or covalent, depending on whether valence electrons are transferred or shared.

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.

The methyl group carbon atom has 6 valence electrons from its bonds to the hydrogen atoms because carbon is more electronegative than hydrogen.

The magnetic fields of the valence electrons do not cancel.

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

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.

The outer ring contains the valence electrons.
