So I mentioned you should be able to identify both how many nodes you have and what a graph might look like of different radial probability distributions.

我说过你们要能够辨认,不同的径向概率分布有多少个节点,以及它的图画出来,大概是什么样的。

Or we could just look at the radial probability distribution itself and see how many nodes there are.

或者我们可以直接,看径向概率分布图,本身看看里面有几个节点。

So we talked about radial nodes when we're doing these radial probability density diagrams here.

我们画这些径向概率分布图的时候,讨论过径向节点。

So here, what I'd like you to do is identify the correct radial probability distribution plot for a 5 s orbital, and also make sure that it matches up with the right number of radial nodes that you would expect.

这里，你们要辨认,哪个是５ｓ轨道的正确概率分布，并且确保它和你们,预期的节点数相符合。

OK. So we should be able to figure this out for any orbital that we're discussing, and when we can figure out especially radial nodes, we have a good head start on going ahead and thinking about drawing radial probability distributions.

我们可以将这种方法,用于任何轨道，当我们可以算出有多少个径向节点的时候，我们就为画出径向概率分布,开了个好头。
