• So what we're doing is filling in those eight electrons following the Aufbau principle, so our first electron is 1s going to go in the 1 s, and then we have no other options for other orbitals that are at that same energy, 1s so we put the second electron in the 1 s as well.

    它会是什么样子呢,我们正在做的是将这8个电子按照奥弗,堡原理进行填充,所以我们第一个电子将会进入,然后我们没有其他的,轨道的选择在同一个能级,所以我们第二个电子也放入

  • Generally, there are a couple of elements that one might set down as in a Petri dish, and wait to see if some chemical reaction might take place, but not at all sure of what it might be.

    一般来说,都有几个元素,作者会它们像放入培养基中一样培养,等待某种化学反应的产生,但对可能的结果却一无所知。

  • This intuitively should make a lot of sense, because we know we're trying to minimize electron repulsions to keep things in as low an energy state as possible, so it makes sense that we would put one electron in each orbital first before we double up in any orbital.

    这个直观上讲得通,因为我们知道尝试去最小化电子排斥力,从而尽可能的保持处于一个较低的能态,所以它讲得通,在我们在同一个轨道放入两个电子之前,我们首先电子放入每一个轨道。

  • We started out with just a simple idea: that you don't want to put all your eggs in one basket and if you had a lot of independent stocks you would want to just weight them equally.

    我们从一个简单的想法开始:,你不想所有的鸡蛋放入一个篮子里,如果你有许多互相独立的股票,你给它们相同的权重。

  • Well what you do is you bomb the food and you use something called the bomb calorimeter that looks like this, and so essentially what you do is you put the food in this device that sits inside water.

  • I'll let you just grok it but you can see it's basically doing what I did over there. Setting up two indices for the two sub-list,it's just walking down, finding the smallest element, putting it into a new list. When it gets to the end of one of the lists, it skips to the next part, and only one of these two pieces will get called because only one of them is going to have things leftovers.

    你们可以大体的浏览一下,但是它们基本就是我在那里所做的事情,为两个子列表设置了两个指针,指针顺着列表走下去,找到最小的元素,放入到一个新的列表中去,当它走到一个列表的尾部时,它会跳到下部分去,两部分中只有一个会被执行,因为只有一个会有元素剩余。

  • Remember we have to put one in each degenerate orbital before we double up on any orbital, so just keep that rule in mind that we would fill one in each p orbital before we a to the second one.

    我们必须,每一个放入简并的轨道,我们每一个电子放在p轨道里,所以规则记在脑子里,我们每一个电子放在p轨道里,在我们放入第二个电子之前。

  • px And I arbitrarily chose to put it in the 2 p x, 2pz we also could have put it in the 2 p y or the 2 p z, it doesn't matter where you double up, they're all the same energy.

    我任意地选择放入至,我们也可以放入2py或,它与你在哪双倍填充没有关系,它们都在相同的能级。
