一价的
adj. univalent ; monovalent ; monobasic

双语例句原声例句
-
卤原子在它们的价电子层含有七个电子，因此是一价的。
Halogen atoms contain seven electrons in their valence shell, and, consequently, are monovalent.
-
我们可以想象比较一下钾离子，与钠离子，它们都同样带有正一价的电荷。
So we could think about comparing the potassium ion to a sodium ion. They have the same charge of plus one.
-
那么，我们可以说--如果我们这里有氖原子,而我们想知道与它等电子的是什么，负一价的氟离子就是与它等电子的，我们还有氧-,氧应该是几价的？
So, we can say that -- if we have neon here and we want to think about what's isoelectronic, -- f minus would be isoelectronic. We also have oxygen -- what would the charge on oxygen be?

So we could think about comparing the potassium ion to a sodium ion. They have the same charge of plus one.
我们可以想象比较一下钾离子,与钠离子，它们都同样带有正一价的电荷。
-
And you would expect that that would be a much stabler compound because, instead of plus one attracting plus one, now you have plus two attracting minus two.
可以预见,这将会是更稳定的化合物，因为不再是一价正离子吸引一价负离子，而是二价正离子吸引二价负离子。
-
So chlorine, if we talk about it in terms of electron affinity, we would be writing that we're actually gaining an electron here, and getting the ion, c l minus.
那么，氯，如果我们要讨论它的电子亲和能，我们会假设它真的得到了,一个电子而变成离子，负一价的氯。
