First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels.

首先我们知道了电子构型，我们可以从，能量最低处开始填。

We had a good fortune to start it with a very top person in the GDMG, feeling it is a very important initiative within his organization.

我们运气很好,可以从GDMG的,一个顶尖人才开始研究，我们认为这一动机,是他的组织的原动力。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。

All right, so now we can move on to the start of today's notes, which is atomic radius.

好，现在我们可以开始讨论今天的讲义了，从原子半径开始。
