共价键(covalent bond),是化学键的一种,两个或多个原子共同使用它们的外层电子,在理想情况下达到电子饱和的状态,由此组成比较稳定的化学结构,像这样由几个相邻原子通过共用电子并与共用电子之间形成的一种强烈作用叫做共价键。其本质是原子轨道重叠后,高概率地出现在两个原子核之间的电子与两个原子核之间的电性作用。

The obtained results show that in Mg(B_(7/8)Be_(1/16)C_(1/16))_2 system,Be-B covalent bond is weaker than B-B covalent bond, and C-B covalent is also weaker than B-B covalent bond,and some B-B bonds are ionic bonds.
结果表明,在Mg(B_(7/8)Be_(1/16)C_(1/16))_2系统中,Be—B共价键和C—B共价键都比B—B共价键弱,而且还存在弱B—B离子键。

这三种成分相互交织,直接形成共价键。
These three components are interwoven, and direct covalent linkages.
共价催化涉及底物与活性位点中的残基或与辅因子形成瞬时共价键。
Covalent catalysis involves the substrate forming a transient covalent bond with residues in the active site or with a cofactor.
配位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。
A coordinate covalent bond is one where both bonding electrons are from one of the atoms involved in the bond.
CO Right, so you take the co here, and we take the valence here, and out of that comes covalent.
好了,然后我们看到,我们可以看到他的化合价,他们成共价键。
OK, so what we've gone through today is we've introduced covalent bonding, and we've figured out a way to quantify it.
好的,那么我们已经经历了,是我们已经介绍了共价键,我们已经想出了一种定量的方法来。
A covalent bond is any time we have a pair of electrons that is shared between two different atoms.
所谓共价键就是我们有两个原子,共用一对电子。
