And, that's a good thing to know because if you come out with an answer that's somewhere near the diameter of the universe and it's supposed to be the diameter of an atom, then you will know that you probably made a mistake.

这是我们需要知道的,因为当你做一道题得到的答案,是宇宙的直径,而正确答案是原子直径时，你能很快发现你的错误。

What does come out, which is very useful is, if you do run the reaction, here's how much heat comes out.

能得到的结果是，如果我们进行这个化学反应，有多少热量放出，当然这也是很重要的。

H And, by the way, if you do this for the hydrogen, H it ought to come out the same.

顺便说一句，如果是，或者如果是。

So, if you can't immediately know, and you don't all have periodic tables in front of you, so that's fine, but if you have a periodic table in front of you, you need to be able to count valence electrons, so work on that if it doesn't come naturally to you in terms of figuring that out.

如果你不能马上想到，而且你手上没有周期表，那还好，但如果你面前有一张周期表，那你就得具备从中查出价电子个数的能力，如果你不能自然而然地想到,请在这方面多下点功夫。

And so, even by units analysis, if the units come out right, you've got a good shot that unless you've really, really messed up, that the answer is going to be right.

甚至在单位分析中，如果你的单位正确，你就能做的很有条理否则会一团糟，而注意了单位你的答案才有可能正确。

If the units come out in meters per second, you will quickly discover that the problems in 3.091 are just not that complicated.

如果你的单位是米每秒，你会很快发现,在3。091中的题目并不复杂。

If the units are supposed to come out in meters per second and you get seconds per meter, what do you figure the chances of that problem being right are?

因为如果单位本应该是米每秒,但你写的是秒每米，你认为这个题目,还有正确的机会吗？

All right, so hopefully if you see any other combination of quantum numbers, for example, if it doesn't quickly come to you how many orbitals you have, you can actually try to write out all the possible orbitals and that should get you started.

所以希望你们如果遇到,任何其它的量子数组合的问题，如果你们不能马上想到有多少个轨道，可以试着先写出所有的轨道,这是个不错的切入点。
