But lower property values and tighter lending requirements mean a harder time getting new loans.

And when we're talking about orbitals in the same state, what we find is that orbitals that have lower values of l can actually penetrate closer to the nucleus.

当我们谈论在相同态的轨道时,轨道事实上，我们发现的,是具有较低l值的,可以穿越到距离原子核更近的地方。

Over here in the lower left corner, we have elements that as a group have very low values of average valence electron energy.

在底层的左侧角落，我们看到以组为单位的,价电子能较低的元素。

But we could, for example, look at a case where we have several different structures that look pretty good, and the one we want to determine as being the lowest energy structure is the one in which the absolute values of the formal charges are going to be lower, so essentially that they have less charge separation.

但是我们可能，比如，遇到一种情况,有好几个候选的路易斯结构看起来都挺好的，这时候我们就需要,通过比较哪个形式电荷的绝对值更低,来决定哪个结构的能量更低，本质上这个结构中分开的电荷更少。
