electropositive

基本解释

In all groups of chemically similar elements the heaviest are the most electropositive.
在化學性質相似的同族元素中，質量越重帶的正電越強。
Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.
比起鉛來，金屬錫的電正性沒有二氧化錫的電負性強，所以無法産生可用的電位差。

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.
産生的結果是，金屬鉛的電正性沒有古典化學理論認爲的那麽強（或者說，更爲電負性）——看起來似乎鉛不適郃用來做電池。

So, at any moment, you know in any bond which is the more electropositive.
在任何時候，你都能判斷誰是正電性的。

Electropositive is down to the left because that is where the metals live.
帶正電性的元素常,在左邊因爲那裡是金屬區。
