And this looks a lot like the average valence electron energy where the lowest values of electronegativity are in the metallic zone and the highest values of electronegativity are on the nonmetallic zone.

这看起来像是平均电子能,最低的电负性在,金属区最高的电负性在,非电子区。

It makes sense. If this is metallic, it is a good electron donor.

这有意义了，如果这是金属，它就是也好的捐赠者。

So, for example, in an electrochemical cell, it would be possible to take the sodium ion, give back its electron, and convert it into a metallic sodium, take the chloride ion, remove its electron, and restore chlorine gas.

所以，例如一个电化学的电池，它可能带有钠离子，让它得到电子，把它变成金属钠，得到氯离子，让它失去电子，作为氯气储存。
