So, this should be pretty straight forward, 100% let's see if we can get close to a 100% on this one, which is how many radial nodes does a 4 p orbital have?

很简单,让我们来看看这题，我们是不是可以接近%,对于一个4p轨道，它有多少个节点？,给你们10秒钟？

And seeing that it's a 4 p has two nodes - let's just write this out since not everyone did get it correct.

因为有些同学没答对,我们还是写一下,如果我们讨论的是4p轨道。

You can see 4s, then 3d, then 4p and then 5s.

你能看到4s层，然后是3d层，然后是5s层。

And now 4p. And now this is 5s.

然后是4p层，现在是5s层。
