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。

And, it says, OK, center the element with the lowest average valence electron energy.

它说，好的,把具有最低平均价电子能的元素画在中心。
