键电子
1、bonding───v.黏合；建立关系；把（货物）存入关栈中（bond的现在分词）；n.人与人之间的关系；键合；粘合
2、covalent bonding───共价键合；共价键；共价键结；共价结合
3、metallic bonding───金属键；金属结合剂；[物]金属键合
4、baby bonding───小面额债券（票面百元以下）
5、excites electrons───激发电子
6、bonding time───粘结时间
7、caesium electrons───铯电子
8、ionic bonding───离子键；离子键结；离子结合
9、valence electrons───[化] 价电子
1、The bonding electrons are electrons, which is at variance with the notion that single bonds are always bonds───成键电子是π电子，这与单键总是σ键的看法不一致。
2、And step six asks us, well, do we have any bonding electrons left?───而第六步问我们，好，我们还有成键电子剩下吗？
3、Step six is thinking about do we have any bonding electrons left?───第六步是想一想我们有多少个成键电子剩下？
4、coordinate covalent bond is one where both bonding electrons are from one of the atoms involved in the bond.───共价键是其中两个键合电子均来自该键所涉及的原子之一的键。
1、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.
2、The way that we can figure this out is using something called bond order, and bond order is equal to 1/2 times the number of bonding electrons, minus the number of anti-bonding electrons.
3、For the sulfur, we start off with 6 valence electrons, minus 4 lone pair electrons, minus 2, taking in account our bonding electrons, so we end up with a formal charge of 0.
