electropositive

基本解释

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。

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。

Electropositive is down to the left because that is where the metals live.
带正电性的元素常,在左边因为那里是金属区。
