So why don't you go ahead and identify the correct electron configuration for carbon, 6 and I'll tell you that z is equal to 6 here.

所以你们为什么不开始,而且识别碳的正确的在你们做作业方面,电子构型，我会告诉你有效电荷量是。

The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.

线性的威力是,一个方程，如果它是个线性方程，那么我就不用再去解他了。

So, how many distinct, so again, we're talking about distinct kinetic energies, a spectrum for the element hafnium, 72 and I'll tell you here that it has a z of 72, so you don't have to spend two minutes searching your periodic table.

好，有多少分立的……还是一样，我们讨论的还是不同的动能，铪元素的光谱中出现，而且我来告诉大家铪的原子序数是，这样你就不用因为在元素周期表中找它,而花费两分钟的时间了。

Let's bind z eh let's bind z to the-- f if I could type it would help-- say, f of 3. OK?

让我们给z赋值--如果我能打字就好了-,比方说？

And the point that I also want to make is the way that they differ, z effective actually differs from the total charge in the nucleus due to an idea called shielding.

我也想指出的一点是它们不同的方式,有效的z事实上不同于原子核的，总电荷量,因为屏蔽效应。

I just go through these equations, 3 but be careful to Z equals three.

我只检查这些方程式，但是注意了，Z等于。

I'm binding a z to be some value, and then I'm going to run this.

我把z绑定到一个值上，然后运行下代码。
