It was probably produced there in the eighth century, and that is supported by the fact that Deuteronomy has affinities with the writings of some prophets we'll be looking at later from the Northern Kingdom of the eighth century, such as the prophet Hosea, and we'll see this when we look at Hosea's writings.

So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.

Absorption is just the opposite of emission, so instead of starting at a high energy level and dropping down, when we absorb light we start low and we absorb energy to bring ourselves up to an n final that's higher.

So, we're going to start with talking about bonding, and any time we have a chemical bond, basically what we're talking about is having two atoms where the arrangement of their nuclei and their electrons are such that the bonded atoms results in a lower energythan for the separate atoms.
那么,下面我们将从成键开始讲起,无论什么时候我们有一个化学键,基本上我们所讨论的,都是如何安排两个原子的原子核的位置,与电子的位置使得成键的两个原子,最终比分开时的能量更低。
That's where we'll start next time.
我们下节课就从这里开始
If we go to the oxygen atom, now we're talking about starting with 6 in terms of valence electrons again, but instead of 2, you can see we have 6 lone pair electrons around the oxygen minus 1/2 of 2, so we have minus 1 is our formal charge.
如果我们分析氧原子的话,现在我们讨论的还是,从六个价电子开始,但孤对电子不再是两个了,你会看到氧周围,有六个孤对电子,再减去二的一半,因此我们有一个负的形式电荷。
The reason in our radial probability distributions we start -- the reason, if you look at the zero point on the radius that we start at zero is because we're multiplying the probability density by some volume, and when we're not anywhere 0 from the nucleus, that volume is defined as zero.
在径向概率密度里,我们开始,如果你们看半径的零点,我们从零点开始,因为我们用概率密,度乘以体积,而当我们,在离核子很近的地方,体积是,所以我们会在这里。
