  • So I think it is important to keep this in mind and I'm gonna be coming back to this a number of times as we talk about the experiments we were doing at the Soen School of management.

    你们要牢记这一点,因为之后,我们会谈到这个问题,做的实验时,我会反复提到这个内容。

  • So, for the most part any time we talk about or draw pointers an arrow suffices, which really 71 in there is a number like 71, which is the literal byte that the F is actually in in RAM, but frankly who cares?

    所以,每次我们讨论,或者用箭头表示指针,在指针里面有一个数字,如,那是F在RAM中的字节,但是谁在乎它呢?

  • We didn't just need that n, not just the principle quantum number that we needed to discuss the energy, but we also need to talk about l and m, as we did in our clicker question up here.

    我们不仅需要n,不仅要这个可以,决定能量的主量子数,还需要m和l,就像我们做这道题这样。

  • And if we talk about chlorine, and both of the chlorines are the same in this case, we start with a valence number of 7 for chlorine, and then we subtract 6, because it had 6 lone pair electrons around each of the chlorine atoms.

    而如果我们讨论氯的话,在这个例子中两个氯的情况都是一样的,从七个价电子开始,然后减去六,因为每个氯原子周围,都有六个孤对电子。

  • And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.

    当我们讲,l是一个量子数时,因为它是量子数,我们知道,它只能去分立的值,它不能取到所有的数,它取一些确定的数。

  • And when we make these comparisons, one thing I want to point out is that we need to keep the constant principle quantum number constant, so we're talking about a certain state, so we could talk about the n equals 2 state, or the n equals 3 state.

    当我们做这些比较时,我想指出的一件事是,我们需要保持常量原则,保持量子数是常数,所以我们在讨论一个确定的态时,我们可以谈论n等于2的态,或者n等于3的态。

  • So, for example, we can move to the next periods in the periodic table. When we talk about a period, we're just talking about that principle quantum number, so period 2 means that we're talking about starting with the 2 s orbitals, period 3 starts with, what we're now filling into the 3 s orbitals here.

    我们可以移至周期表的下一个周期,当我们讨论一个周期时,我们仅仅讨论,周期3以我们所填充的3s轨道,开始填充所以周期2意味着,我们从2s轨道谈起,周期3以我们所填充的3s轨道开始填充。
