And I'll just point out here also, this is a conversion factor you'll use quite frequently -- many of you, quite on accident, will memorize it as you use it over and over again.
你们会经常用到,所以你们可能,会不小心记住它的值,但我们并不会在,任何考试中。
Please don't anybody tell me late - any time after today you didn't know when the mid-term was and therefore it clashes with 17 different things.

And as a reminder, hopefully I don't need to remind any of you, but exam 1 is on Wednesday, so rather than our clicker question being on something from last class, which is exam 2 material, let's just make sure everyone remembers some small topic from exam 1 material, which is the idea of angular nodes.
而作为一个提醒--我希望大家都不需要提醒,但是这周三就要进行第一次考试了,因此我们的这个选择题,不是关于上节课内容的,那是第二次考试的内容,这里只是想确认大家都记得,第一次考试所要求的一些小问题,也就是关于角向节点的概念。
And, one thing I'd like to add to it, and that is, and I told this to my recitation sections that when you do these quizzes, in spite of the fact that it might be trivial in some cases, make sure you carry the units through.

if you don't want to use that, you can also derive it as we did every time, it should intuitively make sense how we got there. But the exams are pretty short, so we don't want you doing that every time, so we'll save the 2 minutes and give you the equations directly, but it's still important to know how to use them.

So, don't start here. And, it happens infrequently, but I've got to tell you, a few years back on the final exam, a couple of people were involved in passing information back and forth.

I don't care how you do it on exams or on problem sets, but you do need to be aware that the 3 d once filled is lower in energy than the 4 s, and the reason you need to be aware of that is if you're asked for the electron configuration now of the titanium ion.
我不关心你们在考试或者,问题集中如何做它,但是你们的确需要知道3d一旦被填充,它的能量是小于4s的,你们需要知道这个的原因,是如果你现在被要求,写出钛离子的电子构型。
