Right, because when we think of an energy diagram, that lowest spot there is going to have the lowest value of the binding energy or the most negative value of binding.

对因为当我们考虑,一个能量图时那里最低的点,是具有最低的结合能,或者最不活跃的结合能。

Because at every point the first thing happens is electron transfer.

因为在任何一个能量点上,最先发生的是电子转移。

The second point of the Aufbau Principle is just energetics.

构造原理的第二点是,它只和能量相关。

And what the second point of Aufbau says is that as electrons begin to fill those levels the differences in energy may shift so that in an unoccupied state certain levels may be in the inverse order from how they are in the occupied state.

构造原理谈到的第二点是,当电子开始布满这些层时,能量差可能会有改变,所以在一个未占据的确定能级,可能与它们占据时,的排布顺序是相反的。
