electropositive
常见例句
- In all groups of chemically similar elements the heaviest are the most electropositive.
在化学性质相似的同族元素中,质量越重带的正电越强。 - Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.
比起铅来,金属锡的电正性没有二氧化锡的电负性强,所以无法产生可用的电位差。
ecocn.org - That has the effect of making metallic lead less electropositive (ie, more electronegative) than classical theory indicates it should be—which would tend to make the battery worse.
产生的结果是,金属铅的电正性没有古典化学理论认为的那么强(或者说,更为电负性)——看起来似乎铅不适合用来做电池。 - So, at any moment, you know in any bond which is the more electropositive.
在任何时候,你都能判断谁是正电性的。
