In an orbital is remember that this area right here at r equals zerio, that is not a node.

例如对于１ｓ轨道,记住这里ｒ等于０处不是一个节点。

And, in fact, these are the only two types of nodes that we're going to be describing, so we can actually calculate both the total number of notes and the number of each type of node we should expect to see in any type of orbital.

事实上，我们只,描述这两种节点，所以我们可以,计算任何轨道中的,总结点数以及各种节点数。

So that's why we saw, for example, in the p orbitals we had one angular node in each p orbital, because l is equal to 1 there.

这就是为什么在ｐ轨道中,每个轨道节点数都是１,因为这里ｌ等于１．

So this is the 1 s star, sigma 1 s star orbital, and what you have in the center here is a node, right in the center between the two nuclei.

这是1s星，sigma1s星轨道，中间这个是节点，它在两个原子核中间。

So what we end up with is one radial node for the 2 s orbital of hydrogen, and we can apply that for argon or any other multi-electron atom here, we also have one radial node for the 2 s orbital of argon.

那意味着它们都是径向节点,所以我们得出的结论是，氢的2s轨道是1个径向节点,我们可以将它应用，到氩或者任意一个多电子原子,对于氩的2s轨道。
